Description:

Abstract:: Geologic Information:
The Redlands 7.5' quadrangle is located in the southeastern margin of the San Bernardino Basin, an extensional region situated in a right-step-over zone within the San Andreas Fault system. The quadrangle is traversed by several important fault zones, including: (1) northwest-trending right-lateral strike-slip faults of the San Andreas system (Banning Fault, the Mission Creek and San Bernardino Strands of the San Andreas Fault, the San Jacinto Fault); (2) northeast-trending normal dip-slip faults that have downdropped the San Bernardino Basin; (3) east-trending contractional faults of the San Timoteo Canyon Fault zone. Some of these faults bound distinctive packages of crystalline basement rock.
Northwest of the Mission Creek Strand of the San Andreas Fault lies an igneous and metamorphic complex characterized by textural and compositional heterogeneity. This terrane, the Wilson Creek block, is strongly gneissose but includes foliated to massive granitoid rocks intimately intermingled with the gneisses. Thin slices of the gneissose complex have been displaced a few kilometers by the San Bernardino Strand of the San Andreas, the modern trace of the San Andreas Fault in the Redlands quadrangle and elsewhere along the southwest margin of the San Bernardino Mountains.
The Mission Creek strand is inferred to lie beneath Quaternary surficial deposits along the southwestern base of the San Bernardino Mountains. This fault is the major strand of the San Andreas Fault zone, has about 100 km of right-slip, and has juxtaposed distinctive crystalline rocks of San Gabriel Mountains-type against the Wilson Creek block and the San Bernardino Mountains.
The Banning Fault probably demarcates an important boundary between rocks of San Gabriel Mountains-type to the north and rocks of Peninsular Ranges-type to the south. This hypothesis is difficult to test because outcrops of the two terranes are several miles apart and between them the trace of the Banning Fault must be inferred beneath surficial deposits and beneath the San Timoteo beds of Frick (1921). The rocks of Peninsular Range-type are very different from those of San Gabriel Mountains-type, and consist of massive to foliated granitoids of monzogranitic, granodioritic, and tonalitic composition.
Much of the Redlands quadrangle is covered with unconsolidated Quaternary surficial deposits of sand and gravel that have accumulated over the last 600,000 years or so. These are thickest on the modern and ancestral flood plains of the Santa Ana River. In the south part of the quadrangle within the San Timoteo and Reche Canyon drainage systems, Quaternary surficial deposits are less extensive and have distribution patterns determined by displacements on the San Timoteo Canyon Fault zone (reverse faulting) and the San Jacinto Fault (strike-slip faulting). In this region, folded and faulted deposits of the San Timoteo beds of Frick, (1921) formed upwarps and downwarps that influenced the evolution of the landscape and its sedimentary deposits.
Digital Data:
This geologic database of the Redlands 1:24,000-scale 7.5' quadrangle, San Bernardino and Riverside Counties, California, was prepared by the Southern California Areal Mapping Project (SCAMP), a geoscience project sponsored jointly by the U.S. Geological Survey (USGS) and the California Geological Survey. The database was created in ARC/INFO (Environmental Systems Research Institute), and includes the following files: (1) a readme file, (2) this metadata file, (3) coverages containing geologic-map data and station-location data, (4) associated data tables, (5) a browse graphic of the geologic-map plot and map-marginal explanatory information (.pdf file), (6) a PostScript graphics file of the geologic-map plot with map-marginal explanatory information, and (7) .pdf files describing map units of the Redlands quadrangle (Description of Map Units) and their geologic age and correlation (Correlation of Map Units).
Purpose:: The geologic database for the Redlands quadrangle was developed as a contribution to the National Cooperative Geologic Mapping Program's National Geologic Map Database, and is intended to provide a general geologic setting of the quadrangle.
Geologic information contained in the Redlands database is general-purpose data that are applicable to land-related investigations in the earth and biological sciences. The term "general-purpose" means that all geologic-feature classes have minimal information content adequate to characterize their general geologic characteristics and to interpret their general geologic history. However, no single feature class may have enough information to definitively characterize its properties and origin. For this reason the database cannot be used for site-specific geologic evaluations, although it can be used to plan and guide investigations at the site-specific level.
Supplemental_Information:: This database is an updated, digital release of an analog map of the Redlands quadrangle released previously in the U.S. Geological Survey Open-File Report (OF) series in 1978 (Morton, 1978). Digital version 1.0 differs from the 1978 analog version in some important ways:
1) Quaternary surficial materials throughout the quadrangle have been reinterpreted based on our analysis of 1938 and 1953 Department of Agriculture (Agricultural Stabilization and Conservation Service, ASCS) aerial photography not examined for the 1978 report.
(2) For many faults, digital version 1.0 provides new geologic data and interpretations: (A) we have interpreted the distribution of the Banning Fault in the subsurface; (B) we have re-interpreted the distribution of fault scarps associated with the Redlands and Reservoir Canyon Faults; (C) we have reintepreted the distribution and mutual relations of faults we group into the Live Oak Fault Zone, and ascribed a reverse-fault origin to this complex; (D) we have interpolated the Mission Creek Strand of the San Andreas Fault as a major structure concealed beneath Quaternary surficial deposits along the southwestern base of the San Bernardino Mountains.
(3) Digital version 1.0 recognizes localized outcrops of San Bernardino Mountains-type rock in the San Bernardino Basin, between the San Bernardino and Mission Creek Strands of the San Andreas Fault. These rocks are part of the igneous and metamorphic complex of the Wilson Creek block, and are critical evidence for our assertion that the Mission Creek Strand of the San Andreas Fault must lie concealed outboard (southwest) of the outcrops.

Use_Constraints:

The Redlands 7.5' geologic-map database should be used to evaluate and understand the geologic character of the Redlands quadrangle as a whole. It should not be used as a detailed map for purposes of site-specific land-use planning or site-specific geologic evaluations.
The database is sufficiently detailed to identify and characterize many actual and potential geologic hazards represented by faults and landslides and posed by ground subsidence and earthquake-generated ground shaking. However, it is not sufficiently detailed for site-specific determinations or evaluations of these features. Faults shown do not take the place of fault-rupture hazard zones designated by the California State Geologist (see Hart, 1988).
Use of the Redlands geologic-map database should not violate the spatial resolution of the data. Although the digital form of the data allows the scale to be manipulated at the discretion of the user, detail and accuracy issues that are inherent to map-scale limitations similarly exist in the digital data. The fact that this database was constructed and edited at a scale of 1:24,000 means that higher-resolution data generally are not present in the dataset. Therefore, plotting at scales larger than 1:24,000 will not yield greater real detail, although enlarged plots may reveal fine-scale (artificial) irregularities below the intended resolution of the database. Although the data set may incorporate higher-resolution data at a few places, the resolution of the combined data-base output will be limited by the lower-resolution data.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: The combination of detailed and reconnaissance techniques used to generate the Redlands quadrangle database has yielded a data set whose quality necessarily varies from location to location. Some areas were examined in great detail in order to solve specific geologic problems or to clarify the description or geologic relations of a particular map unit. Other areas were examined less carefully or were not examined at all. As a result, some parts of the Redlands data set have greater attribute accuracy and represent greater attribute confidence than others.
ATTRIBUTE ACCURACY
The attribute-accuracy statement for the Redlands database incorporates four elements: (1) map-unit description and attribution, (2) geotechnical standards against which the observations are measured, (3) map-unit identification, and (4) description of linear and planar geologic structures.
Map-unit description and attribution:
Geologic-map units in the Redlands quadrangle database were described using standard field methods (see Process_Description 1 of 6). Consistent with these methods and consistent with the time available to assemble the data set, the database authors have assigned standard geologic attributes to geologic lines, points, and polygons identified in the database.
Geotechnical standards for geologic descriptions:
Plutonic rock classification: Plutonic rocks and their deformed equivalents are classified in accordance with the International Union of Geological Sciences Subcommission on the Systematics of Igneous Rocks (1973; Streckeisen, 1976).
Sedimentary rock classifications: Sandstones are classified in accordance with the scheme suggested by Friedman and Sanders (1978, Table 7-4). For all sedimentary materials, bedding-thickness classification follows Ingram (1954) and grain-size classification follows Wentworth (1922).
Surficial-materials classification: Surficial materials are mapped and classified according to a southern California-wide classification scheme being developed by the Southern California Areal Mapping Project (SCAMP).
Terminology for slope-failure deposits (landslides and other slope-failure types) follows Varnes (1978).
Color classification: The matrix color of surficial materials and their pedogenic soils is classified according to the Munsell soil-color charts (Munsell, 1975). Bedrock colors also are classified according to the Munsell system, supplemented by the Rock-Color Chart distributed by the Geological Society of America (reprinted 1970).
Map-unit identification:
Geologic-map units in the Redlands quadrangle represent packages of geologic materials whose overall physical properties differ sufficiently from other such units as to constitute discrete mappable entities. From localities in the quadrangle where map units first were recognized and defined, they were extended to other areas through a mapping process that includes (a) direct outcrop observation, (b) interpretation of subsurface boring logs, and (c) aerial-photographic extrapolation into areas where site observation was not conducted. The coverage red_obs indicates the density of observation and data stations in the Redlands quadrangle, and is a measure of whether a map unit at a particular location was identified on the basis of hands-on data or extrapolation.
Map-unit boundaries (geologic contacts) and faults identified along mapping traverses typically were extended laterally by using aerial photographs and binoculars to project or interpolate the contact or fault to its next recorded occurrence along a nearby traverse. Only rarely were individual geologic contacts or fault lines walked out to determine their variability and character throughout the map area. The bounding contacts of surficial units and the location of fault scarps that traverse the units were plotted by using a PG-2 photogrammetric plotter that allows location accuracy equivalent to the accuracy standard for the topographic-contour base.
Description geologic structures
Geologic structure (planar structure displayed by lines, structure at specific points) in the Redlands quadrangle are described and attributed according to the scheme described by Matti and others (1997a, b). These classifications generally follow conventional schemes for classifying geologic lines and points (Reynolds and others, 1995).
ATTRIBUTE CONFIDENCE
For version 1.0 of the database, the coverage red_obs is a proxy for attribute confidence: the number of direct observations within a map unit from place to place in the quadrangle proxies for the confidence with which the unit and its attributes are believed to be accurately identified. Future releases of the Redlands data set will delineate a more objective, empirical basis for map-unit identification and attribute accuracy (map-unit and attribute confidence).

Logical_Consistency_Report:

Polygon and chain-node topology present.
The areal extent of the map is represented digitally by an appropriately projected (Polyconic projection), mathematically generated box. Consequently, polygons intersecting the lines that comprise the map boundary are closed by that boundary. Polygons internal to the map boundary are completely enclosed by line segments that are themselves a set of sequentially numbered coordinate pairs. Point data are represented by coordinate pairs.

Completeness_Report:

The geologic map and digital database of the Redlands 7.5' quadrangle contain new data that have been subjected to scientific peer review and are a substantially complete representation of the current state of knowledge concerning the geology of the quadrangle.
Information for geologic units, geologic contacts, and faults by necessity is generalized. Although derived from data collected at individual observation stations, the characteristics of map units, their bounding contacts, and faults have been averaged and reduced to attributes that describe each map unit and each line element as a whole. This averaging process is necessary because of the intrinsic variability that geologic units, contacts, and faults display spatially: in detail, their characteristics necessarily vary from place-to-place, although certain core attributes persist. To account for this variability and yet still characterize the major defining attributes of geologic entities, the database authors have selected and archived certain geologic characteristics but omitted others. In such cases, details were sacrificed in the interest of defining the average character of the geologic features.
Map-unit completeness: For map-unit polygons, version 1.0 of the Redlands database does not exploit the full potential afforded by the data-model and attribute scheme proposed by Matti and others (1997a). The file red_geo.pat contains limited information about polygon themes such as geologic age and the thickness of geologic-map units (where appropriate or where known), as well as information about unique attributes that distinguish a map unit within a polygon or a perticular subset of polygons. Additional lithologic-attribute data are available in the INFO data table red_summ.rel, including age-related data and major rock type. Other than this minimal information, however, the Redlands database for geologic-map units (red_geo) lacks the comprehensive information content of the .pdf files (red_dmu.pdf and red_cmu.pdf).
The following data fields in the INFO table red_geo.pat for the geologic-map unit coverage contain no information:
THICK: Information about the stratigraphic thickness of geologic units is not included because such information was not obtained for digital version 1.0 of the Redlands quadrangle database.
SOURCE: Information about the source of geologic information for geologic map units is not included because in all cases such information for the Redlands database derives from the database authors.
Line and Point Completeness: For line and point data, the Redlands database exploits the attribution scheme proposed by Matti and others (1997a,b). This scheme allows geologic elements represented as lines (geologic contacts, faults, fold axes, geomorphic features) and points (bedding orientations, foliation orientations, fault dips) to be assigned a full spectrum of attributes ranging from contact and fault type to geologic age of linear and point features. Some of these attributes are embedded directly within the line and point data bases (.aat and .pat, respectively). Most line and point attributes are stored as codes in two INFO data tables (lines.rel and points.rel).
A complete description of the attribute-coding schemes for SCAMP polygon, line, and point data is available in U.S. Geological Survey Open-File Reports OF-97-859, OF-97-860, and OF-97-861 (full source citations follow):

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Nationwide geologic-map accuracy standards for geologic line and point features have not been developed and adopted by the U.S. Geological Survey and other earth-science entities. Until such standards are developed, the Southern California Areal Mapping Project (SCAMP) uses internal map-accuracy standards for 1:24,000-scale geologic maps produced by the project.
In the Redlands 1:24,000 scale quadrangle, geologic lines are judged to meet the map-accuracy standard if they are located to within ±15 meters relative to topographic or cultural features on the base map. Within the database, line data that are judged to meet the map-accuracy standard are denoted in the data table lines.rel by the attribute code .MEE. (meets); line data that may not meet the map-accuracy standard are denoted by the attribute code .MNM. (may not meet). On geologic-map plots and other plots generated from the geologic database, line data that are judged to meet the map-accuracy standard are denoted by solid lines; line data that may not meet the map-accuracy standard are denoted by dashed or dotted lines.
In the database and on geologic-map plots, no cartographic device exists for denoting the map-accuracy for geologic-point data (symbols for bedding, foliation, lineations, etc.).
Three sources of positional error exist for geologic elements in the Redlands quadrangle database:
(1) Positional accuracy of field observations: observation stations (data localities) were located either on aerial photographs or on the topographic basemap of the Redlands quadrangle by referencing hypsographic and planimetric features on the basemap.
(2) Transfer of line and point data from aerial photographs to the topographic base: For bedrock geologic materials, point data, contacts and faults were visually transferred to scale-stable copies of the topographic base map. For most surficial geologic materials, geologic contacts and fault scarps were transferred to the base map through the use of a PG-2 sterographic plotter that allows geologic elements to be located with an accuracy and precision equivalent to the standard for the topographic-contour base.
(3) Positional fidelity during digital data processing: the maximum transformation Root Mean Square (RMS) error acceptable for 7.5' quadrangle transformation and data input is 0.003 (1.8 meters). The horizontal positional accuracy line and point entities was checked by visual comparison of hard-copy plots with base-stable source data.

The Pictorial Crafts aerial photography provides true-color rendering of geologic and geomorphic features in the Redlands quadrangle and throughout the San Bernardino Basin. The E-W flight lines were the primary aerial-photography resource used by the authors to locate the position of observation stations and to plot the positions of linear geologic structures (geologic contacts, faults, fold axes). Although their 1975 vintage post-dates urbanization that obscures some geologic features, the photography was helpful in recognizing geologic features whose color is a distinguishing characteristic.

Source_Contribution:

The ASCS photography provides systematic aerial-photographic cover of the Redlands quadrangle and the rest of the San Bernardino Basin, along N-S flight lines. This orientation contrasts with the typical E-W orientation of most photographic series, and provides a different perspective of geologic and geomorphic features. Because the ASCS photography pre-dates much urbanization that obscures land-form features, it was helpful in recognizing geologic and geomorphic features that have been obliterated by human activities in the last 50 years or so. The database authors used the 1952 ASCS photography to augment and refine observations made using the 1975 Pictorial Crafts photography, and to delineate features in the Redlands municipal area.

Source_Contribution:

The 1938 ASCS photography provides the most regionally extensive early-vintage aerial images available for southern California, including the Redlands quadrangle. The 1938 photography pre-dates much urbanization that obscures land-form features, and thus was helpful in recognizing geologic and geomorphic features that have been obliterated by human activities in the last 60 years or so. The database authors used the 1938 photography to augment and refine observations made using the 1975 Pictorial Crafts photography, and to delineate pre-urbanization features in the northwestern part of the quadrangle.

The Spence aerial photography consists of a single flight line flown along the San Andreas Fault in southern California, including the Redlands quadrangle. The 1930 photography pre-dates much urbanization that obscures land-form features, and thus was helpful in delineating geologic and geomorphic features (fault scarps, shutter ridges, lineaments) that have been obliterated by human activities in the last 70 years or so. The database authors used the 1930 Spence photography to interpret geomorphic details of the San Andreas Fault Zone (San Bernardino Strand).

Source_Contribution:

The 1978 analog geologic map of the Redlands quadrangle is the source of geologic line, point, and map-unit data for many bedrock map units in digital version 1.0. Lithologic, structural, and stratigraphic data for sedimentary deposits of the San Timoteo beds of Frick (1921) are retained, as are boundaries and structural orientations of crystalline bedrock units. Most faults are the same as in the analog version.

Process_Step:

Process_Description:: Field Methods
The geologic information contained in the database and on the geologic-map plot was generated by the U.S. Geological Survey using a combination of reconnaissance and detailed mapping techniques. The field data were collected and plotted on aerial photographs and on a 1:24,000-scale basemap (U.S. Geological Survey, 1:24,000 Redlands 7.5' quadrangle, 1967, photorevised, 1980)
Bedrock map units were described, mapped, and interpreted on the basis of traverse-mapping methods. Along each traverse, geologic observations are made and recorded at various observation stations whose postitions are stored in the coverage red_obs. Information recorded at these stations provides the basis for the identification and characterization of each bedrock map unit. Map-unit boundaries (geologic contacts) and faults identified along each traverse typically were extended laterally by using aerial photographs and binoculars to project or interpolate the fault or contact to its next recorded occurrence along a nearby traverse. A few sedimentary-layering attitudes were determined through binocular observation rather than from site determinations; these are identified in the database and on the geologic-map plot.
Surficial-materials map units were described, mapped, and interpreted on the basis of aerial-photographic interpretation augmented by observation at specific stations. The bounding contacts of each surficial unit and the location of fault scarps that traverse the units were plotted by using a PG-2 photogrammetric plotter that allows location accuracy equivalent to the accuracy standard for the topographic-contour base. The coverage red_obs shows the position of observation stations used to determine geologic characteristics of the surficial map units.

Process_Description:: Analog Geologic-map Preparation Methods
The digital geologic-map database was produced from geologic linework drafted on a 1:24,000-scale greenline chronoflex of the Redlands 7.5' quadrangle using a 0.18 rapidograph drafting pen. Source materials include: (1) paper field sheets produced by each map author; (2) annotations made by each author on aerial photographs; (3) pencil linework generated by PG-2 stereographic plotter on a scale-stable 1:24,000-scale chronoflex of the Redlands 7.5' quadrangle.
The basemap image (red.tif) was prepared by scanning a scale-stable blackline .007-mil clear film of the U.S. Geological Survey, 1:24,000-scale Redlands 7.5' quadrangle topographic map (1967, photorevised, 1980). Scanning was done using an Anatech Eagle 4080 monochrome 800 dots-per-inch scanner at a resolution of 500 dpi. The raster scan was converted to a monochromatic image in ARC/INFO. No elements of the base layer are attributed. The base map is provided for reference only.
Process_Date: 1990-1991

Process_Step:

Process_Description:: Digital Data Capture and Editing
Geologic data for the Redlands 7.5' quadrangle were captured in different stages using different techniques. (1) Geologic-line information in the southern third of the quadrangle was digitized and simultaneously converted to ARC/INFO coverages through the application and utilization of the graphical user interface ALACARTE developed by the USGS (Fitzgibbon, 1991; Fitzgibbon and Wentworth, 1991; Wentworth and Fitzgibbon, 1991) running on a Data General Aviion workstation. (2) For the northern two-thirds of the quadrangle, geologic-line information was captured by scanning a scale-stable 0.010-mil clear-film positive of linework drafted by the authors on greenline milar. The clear-film positive was scanned by Optronics, Inc. to produce an 800 DPI raster file, and the raster image was converted to vector format by Optronics, Inc. using proprietary auto-vectorizing software. (3) For the entire quadrangle, geologic-point data were captured using ARC/INFO v. 7.0.4 software using a Sun SPARC20 computer system running Solaris v. 2.4.
The database was edited and tagged in ARC/INFO v. 7.0.4 and v. 7.1.1 using a Sun SPARC20 computer system running Solaris v. 2.4.

Overview_Description:

Entity_and_Attribute_Overview:

The ARC/INFO version of the Geologic map and digital database of the Redlands 7.5'quadrangle consists of six coverages:

red_geo (geologic map units and geologic-line entities)
red_pts (geologic point features)
red_obs (distribution of data stations)
red_str (anticlinal and synclinal structures)
red_orn (geologic line ornamentation)
red_ldr (map-unit label leaders)

Three additional INFO data tables are included in the data set: red_summ.rel (provides general information about each geologic-map unit, including general lithologic features, geologic age, and geologic origin which applies to all polygons of a specified map unit)
lines.rel (provides information about geologic features displayed as lines on the map. For a complete description of attributes in lines.rel, refer to USGS Open-File Report 97-861 – see Entity_and_Attribute_Detail_Citation)
points.rel (provides information about geologic features displayed as points on the map. for a complete description of attributes in points.rel, refer to USGS Open-File Report 97-859 (see Entity_and_Attribute_Detail_Citation).
1) The coverage red_geo contains information about geologic-map units (represented by polygons) and planar geologic features that bound or break them (e.g. geologic contacts, and faults) represented by lines. The polygons have cartographic and geologic attributes contained in red_geo.pat; the lines have cartographic and geologic attributes contained in red_geo.aat. For display purposes, the geology coverage contains two annotation subclasses: geo contains unit labels, and fault contains formal fault names.
2) The coverage red_pts contains analyzable structural data including information that describes the types and orientation of planar and linear geologic features such as bedding, foliation, fault-plane dip, and fold-hinge plunge. One annotation subclass is included in the geologic points coverage which displays the respective dip and plunge values associated with individual point data.
3) The coverage red_obs contains point data that repesent the locality of data stations associated with multiple authors and sources, all of which have contributed geologic data. The locality data serve several purposes: (1) as a proxy for author confidence in unit identification, (2) as a means of identifying each author's contribution, and (3) as a means of identifying data from sources other than the USGS authors. One annotation subclass, obs, identifies five particular locations: four Natural Resources Conservation Service (NRCS) soil profile description localities and one U.S. Geological Survey Water Resource Division (WRD) well-log data locality.
4) The coverage red_str contains geologic-line data that represent the traces of axial planes for anticlines and synclines.
5) The coverage red_ptsorn stores point data that represent ornamentation for geologic lines (e.g. strike slip arrows, bar and ball on down-thrown block, etc.)
6) The coverage red_ldr contains annotation leaders that point to unit labels that are placed outside the perimeter of a particular geologic polygon. These cartographic line entities are attributed with only a single attribute, L-SYMB, and all have the same value, 1.

Attribute:

Attribute_Label: TAG
Attribute_Definition:: A reference label for subgroups of polygons of the geologic-map unit identified by LABL. Every polygon subgroup has certain attributes in common with all other polygons of the map unit, but each subgroup has unique, distinguishing attributes that warrant recognition in the database although they do not provide a basis for recognizing new map units (for example, geographic variations in properties such as grain size, thickness, and clast compositiion).
TAG serves one additional purpose: it functions as the relate item that associates each polygon with its attributes stored in the polygon-attribute data table, RED_SUMM.REL.
TAG is defined as LABL followed by an upper-case letter, e.g., QwA, QwB, or QwC, etc. Most map units in the Redlands databse have only one TAG designation, TAG A; map units having polygon subsets representing characteristics sufficiently distinct from those of the overall unit include: Qw (QwA, QwB), Qw1 (Qw1A, Qw1B), Qw2 (Qw2A, Qw2B), Qya1 (Qya1A, Qya1B), Qya3 (Qya3A, Qya3B, Qya3C), Qya5 (Qya5A, Qya5B), Qvof3 (Qvof3A, Qvof3C).
