Description:

Abstract:: This data set maps and describes the geology of the Lakeview 7.5' quadrangle, Riverside County, California. The quadrangle encompasses part of the northern Peninsular Ranges Province. Tonalitic granitic rocks of the Cretaceous Peninsular Range batholith dominate the bedrock areas, and include rocks ranging in composition from monzogranite to gabbro. The Lakeview Mountains are underlain chiefly by tonalite of the Lakeview pluton and related rocks. In the northeastern corner of the quadrangle, Tertiary sedimentary rocks of the San Timoteo beds of Frick (1921) and Mount Eden Formation of Fraser (1931) rest on Paleozoic schist, quartzite, gneiss, and marble having a well developed east dipping foliation. The Tertiary formations are much more extensively exposed in the San Timoteo Badlands to the northeast and southeast. These Tertiary and Paleozoic units are separated from the Lakeview Mountains by the San Jacinto Valley, which locally contains up to 3,000 m of Quaternary sediments. Two strands of the seismically active San Jacinto Fault zone bound the Valley, the Claremont Fault on the northeast side, and the Casa Loma Fault on the southwest side. Numerous cracks and fissures related to both groundwater withdrawal and tectonic movements are developed in the Quaternary sediments, especially in the northern part of the quadrangle.
Created using Environmental Systems Research Institute's ARC/INFO software, the database consists of the following items: (1) a map coverage containing faults, geologic contacts and units, (2) a coverage showing structural data, (3) a coverage containing geologic unit annotation and leaders, and (4) five additional INFO data tables (.rel) that contain detailed, coded, geologic information such as texture, fabric, color, and mineralogy and (5) line and point dictionaries, lines.rel and points.rel. These additional data are accessible to the user through the utilization of ARC/INFO relate environments and provide the user access to as much or as little of the encoded data as required. In addition, the data set includes the following graphic and text products: (1) A PostScript graphic plot-file containing the geologic map, topography, cultural data, a Correlation of Map Units (CMU) diagram, a Description of Map Units (DMU), and a key for point and line symbols, and (2) PDF files of this Readme (including the metadata file as an appendix), the poly_attrib_code.txt (the polygon attribute coding), and the graphic produced by the Postscript plot file.
The geologic map database contains original U.S. Geological Survey data generated by detailed field observation and by interpretation of aerial photographs. Within the database, geologic contacts are represented as lines (arcs), geologic units as polygons, and site-specific data as points. Polygon, arc, and point attribute tables (.pat, .aat, and .pat, respectively) uniquely identify each geologic datum.
Purpose:: The data set for the Lakeview quadrangle has been prepared by the Southern California Areal Mapping Project (SCAMP), a cooperative project sponsored jointly by the U.S. Geological Survey and the California Division of Mines and Geology. The Lakeview data set represents part of an ongoing effort to create a regional GIS geologic database for southern California. This regional digital database, in turn, is being developed as a contribution to the National Geologic Map Database of the National Cooperative Geologic Mapping Program of the USGS.
The digital geologic map database for the Lakeview 7.5' quadrangle has been created as a general-purpose data set that is applicable to other land-related investigations in the earth and biological sciences. For example, it can be used for groundwater studies in the San Bernardino basin, and for mineral resource evaluation studies, animal and plant habitat studies, and soil studies in the San Bernardino National Forest. The database is not suitable for site-specific geologic evaluations.
Supplemental_Information:: Within the geologic map database, map units are identified by standard geologic map criteria such as formation-name, age, and lithology. The authors have attempted to adhere to the stratigraphic nomenclature of the U.S. Geological Survey and the North American Stratigraphic Code, but the database has not received a formal editorial review of geologic names.
Geologic map unit labels entered in database items LABL and PLABL contain substitute characters for conventional stratigraphic age symbols: Paleozoic appears as 'Pz' in LABL and as '|' in PLABL. The substitute characters in PLABL invoke their corresponding symbols from the GeoAge font group to generate map unit labels with conventional stratigraphic symbols.

Access_Constraints: None

Use_Constraints:

The Lakeview 7.5' geologic-map database should be used to evaluate and understand the geologic character of the Lakeview 7.5' quadrangle as a whole. The data should not be used for purposes of site-specific land-use planning or site-specific geologic evaluations. The database is sufficiently detailed to identify and characterize geologic materials and structures. However, it is not sufficiently detailed for site-specific determinations.
Use of this digital geologic map database should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was compiled and edited at a scale of 1:24,000 means that higher resolution information may not have been uniformly retained in the dataset. Plotting at scales larger than 1:24,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, although higher resolution data is incorporated in parts of the map, the resolution of the combined output will be limited by the lower resolution data.

Data_Set_Credit:

Technical review by M. Dawson and F. Miller led to significant improvements that eventually were reflected in aspects of the database, the plot file, and in the description of the geologic units of the Lakeview 7.5' quadrangle. Digital review by R.W. Graymer has allowed us to prepare a much improved product.
Geologic mapping and digital preparation of this report were sponsored jointly by (1) the National Cooperative Geologic Mapping Program of the U.S. Geological Survey, (2) the California Division of Mines and Geology, and (3) the Southern California Areal Mapping Project (SCAMP). The digital preparation of the data set was carried out by Rachel Alvarez and Gary Patt at the SCAMP Geographic Information System laboratory in Riverside, and by Pamela M. Cossette at the USGS Mineral Resources Program GIS lab in Spokane, Washington.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: Geologic-map units in the Lakeview quadrangle database were described using standard field methods. Consistent with these methods, the database author has assigned standard geologic attributes to geologic lines, points, and polygons identified in the database.
Nation-wide geologic-map accuracy standards have not been developed and adopted by the U.S. Geological Survey and other earth-science entities. Until such standards are adopted, the SCAMP project has developed internal map-accuracy standards for 1:24,000-scale geologic maps produced by the project.
Geologic lines and points on 1:24,000 scale geologic maps are judged to meet SCAMP's internal map-accuracy standards if they are located to within +/-15 meters, relative to topographic or cultural features on the base map.
Lines and points that meet (or may not meet) this SCAMP internal map-accuracy standard are identified both in the digital database and on derivative geologic-map plots. Within the database, line and point data that are judged to meet the SCAMP internal map-accuracy standard are denoted by the attribute code .MEE. (meets) in the appropriate data table; line and point data that may not meet the SCAMP internal map-accuracy standard are denoted by the attribute code .MNM. (may not meet).
On any derivative geologic-map plot, line data that are judged to meet the SCAMP internal map-accuracy standard are denoted by solid lines; line data that may not meet the SCAMP internal map-accuracy standard are denoted by dashed or dotted lines. There is no cartographic device for denoting the map-accuracy for geologic-point data (eg. symbols representing bedding, foliation, lineations, etc.).

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 which 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 Lakeview 7.5' quadrangle contain new data that have been subjected to rigorous review and are a substantially complete representation of the current state of knowledge concerning the geology of the quadrangle.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: The maximum transformation RMS error acceptable for 7.5' quadrangle transformation and data input is 0.003 (7.6 meters). Horizontal positional accuracy was checked by visual comparison of hard-copy plots with base-stable source data.

Entity_and_Attribute_Information:

Overview_Description:

Entity_and_Attribute_Overview:: Version 1.0 of the Lakeview 7.5' quadrangle comprises three ARC/INFO coverages, of which two contain geologic data and one contains cartographic features: lkvw_geo (geology), lkvw_pts (structural point data), and lkvw_anno (geologic unit annotation and leaders). Geospatial entities in ARC/INFO coverages have the following software-defined attributes: <cover>.pat contains AREA, PERIMETER, cover#, and cover-ID; <cover>.aat contains FNODE#, TNODE#, LPOLY#, RPOLY#, LENGTH, cover#, and cover-ID. User-defined attributes are described in detail below.Two INFO tables, lines.rel and points.rel provide a full description of each of the geologic line and point features in the database. Full source citations are provided in the Entity_and Attribute_Detail_Citation section of this metadata document.
1) The coverage lkvw_geo includes a polygon feature attribute table (lkvw_geo.pat) that describes the geospatial distribution of rock units represented in the Postscript (.ps) and Portable Document Format (.pdf) plotfiles of the geologic maps and an arc feature attribute table (lkvw_geo.aat) that describes the contacts and faults that bound rock-unit polygons. Line and point identity data are recorded in the .aat and .pat using a system of identity codes. Two INFO tables, lines.rel and points.rel, provide a full description of each of the geological line and point codes in the database. For display purposes in the .ps and .pdf geologic maps, the geology coverage includes one annotation subclass: anno.fault, which contains formal fault names. In addition, the item TAG allows the user to access (relate to) a series of INFO data tables that contain additional, detailed, coded geologic data. A complete description of the polygon, line, and point data coding schemes is available in U.S. Geological Survey Open-File Reports 97-859, OFR 97-860, and OFR 97-861 (full source citations follow).
Five INFO data tables are included in the Lakeview database: lakeview_genesis.rel provides data summarizing the genesis of each of the major rock types that occur within a particular map rock unit, lakeview_summary.rel provides general information about a rock unit, lakeview_lithology.rel contains lithologic attributes for the main and secondary lithologic types in the geologic-map unit, lakeview_protolith.rel describes rock type protoliths, and lakeview_structure.rel contains geologic structural data. The tables have identical architecture. The item TAG serves as the relate item and there are five additional feature attribute items, LITH1...LITH5, that represent the major rock types within a rock unit. Lakeview_structure.rel contains an item STRHIST that contains attributes that describe the structural history of a particular unit.
2) The coverage lkvw_pts includes a point attribute table (lkvw_pts.pat) that describes both the types and orientation of bedding, foliation, and lineation. An annotation subclass displays the dip or plunge values associated with the point data.
3) The coverage lkvw_anno includes an arc attribute table (lkvw_ldr.pat) that describes annotation leaders and one annotation subclass, anno.geo, which contains unit labels derived from PLABL. Unit symbols that are placed outside the perimeter of a particular polygon identify that polygon with annotation leaders.

Attribute:

Attribute_Label: TAG
Attribute_Definition:: A reference label for subgroups of polygons of the geologic-map unit identified by LABL. Each polygon subgroup has certain attributes in common with all other polygons of the map unit. However, each subgroup may have unique, distinguishing attributes which warrant recognition in the database although those distinguishing characteristics do not warrant recognition as new map units.
TAG is defined as LABL followed by an upper-case letter, e.g., QwA, QwB, or QwC, etc. Map units in the Lakeview quadrangle are assigned an A tag designation except for Qyv (QyvA, QyvB and QyvC) and Qyf (QyfA, QyfB and QyfC).
TAG serves one additional purpose: it functions as the relate item that associates each polygon with its attributes stored in the five polygon-attribute data tables identified in the overview description.
