Abstract:

The Lockwood Valley quadrangle is located in the western Transverse Ranges of California, about 10 km southwest of Frazier Park. It includes the western flank of Frazier Mountain, southern Lockwood Valley, and a region of the Los Padres National Forest near northern Piru Creek.
The oldest rocks are mostly biotite augen gneiss, in the hanging wall of the Frazier Mountain thrust and in a large body south of the thrust. A U-Pb zircon age for the gneiss is 1690+5 Ma (W. Premo, unpublished data). Two Cretaceous intrusive rocks are named the quartz monzonite of Sheep Creek and the coarse-grained granodiorite of Lockwood Peak. A U-Pb zircon age on the latter is 76.05+0.22 Ma (W. Premo, unpublished data).
The northeastern edge of a large Eocene marine basin, comprising the sandstones, shales, and conglomerates of the Juncal Formation, occupies the southwestern 25 percent of the quadrangle. Miocene fluvial rocks, including coarse boulder conglomerates, sandstones, and shale, of the Caliente Formation crop out mostly in the northwestern part of the quadrangle. Commercially exploitable Lockwood Clay unconformably overlies the Caliente, which, in turn, is overlain by the mostly fluvial Pliocene Quatal Formation.
Two major south-directed thrusts, the Frazier Mountain thrust and the South Frazier Mountain thrust, place crystalline rocks over Miocene and Pliocene sedimentary rocks. The South Frazier Mountain thrust is transected by the newly recognized, north-directed Lockwood Peak reverse fault. In addition, the newly recognized south-directed Yellowjacket thrust displaces rocks of the Pliocene Quatal Formation.

Purpose:

To update and reinterpret earlier geologic mapping, and to achieve a uniform regional geologic database.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Data were entered and checked by the geologist that made the observations. The attributes of this geospatial data set consist of text identifiers and numeric codes that indicate the identity of the geologic unit or type of geologic feature, and determine how each feature is colored or symbolized. To check attribute accuracy, a color check plot was visually compared to the geologist's original compilation. Discrepancies between the digital geospatial dataset and the original analog compilation were corrected as needed. Machine-created listings of unique attribute values were used to identify spelling errors or other inconsistencies, and corrections were made as needed.

Logical_Consistency_Report:

Map elements were visually checked for overshoots, undershoots, duplicate features, polygon attributes, and other errors. Automated (ARC/INFO) routines were also used to check the databases for polygon label errors, line or point attribution errors, sliver polygons, dangling arcs, intersection errors, and projection information. The map was reviewed by one other geologist for consistency with basic geologic principles and general conformity to USGS mapping standards.

Completeness_Report:

Data are complete: no features were eliminated or generalized. Unit properties are described in the text explanation.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Lines were primarily mapped by ground investigation and photointerpretation of 1:24,000-scale color aerial photographs. These lines were digitized from the topographic field sheets and from annotated aerial photographs. Most digitized positions on the map are estimated to have about 20 m horizontal accuracy. Additional point observations were added using positions determined by a Rockwell PLGR-96 GPS unit with horizontal accuracy of about 10 meters. There is no elevation data in the database.

Lineage:

Process_Step:

Process_Description:

Polygons, lines, and points representing geologic features and data points were digitized from scale-stable compilation materials using the GSMCAD public domain program (USGS Open-File Report 96-007).

The data is supplied in ARC/INFO export and shape file formats.
DATABASE STRUCTURE - ARC/INFO ====================================
The database of the map consists of three coverages (root name = lw). This GIS database includes related look-up tables, which store detailed attribute information. Arc/Info relates for each coverage are saved in a file named <covername>.rel. Use the RELATE command with the restore argument at the arc prompt to make the relates active. Alternatively, in Arctools, use the Relate environment: open dialog in the Manage - Relates flyout menu under the Arctools menu to make the relates active.
lwpoly coverage: Contains all contact lines and labelpoints for each geologic polygon. In the lwpoly.pat INFO file the LABEL item indicates the rock unit label (abbreviation) used to label the unit on the map. The DESC item contains the formal or informal unit name. The SOURCE item contains the numeric code used to identify the data source for the rock unit. The SYMBOL item contains the shadeset symbol number used by ArcInfo to plot a filled/shaded polygon. The symbol numbers in this coverage refer to the color524.shd shadeset.

lwpnt coverage: Contains points recording site-specific observations and measurements, such as strike and dip of bedding. In the lwpnt.pat INFO file the PTTYPE item lists the type of point symbol, e.g., strike and of inclined bedding. The SYMBOLCD item lists the marker symbol used by ArcInfo to identify the type of structural map symbol. Symbol numbers refer to the geoscamp2.mrk markerset. The STRIKE item contains the strike of bedding. Strike is an azimuthal angle (measured in degrees from 0 to 360 in a clockwise direction from North). The DIP item contains the dip of bedding. This value is an angle measured (in degrees 0 to 90) down from the horizontal; thus a horizontal dip is 0 degrees and a vertical dip is 90 degrees. The BEARING item contains the bearing of lineation. Bearing is an azimuthal angle (measured in degrees from 0 to 360 in a clockwise direction from North). The PLUNGE item contains the plunge of lineation. This value is an angle measured (in degrees 0 to 90) down from the horizontal; thus a horizontal plunge is 0 degrees and a vertical plunge is 90 degrees. The CALCANG item contains an interim value used to calculate SYM$ANGLE. The SYM$ANGLE item is the angle used to mathematically rotate the map point symbol to its proper orientation on the map. This item was set equal to the pseudoitem '$ANGLE' (calc SYM$ANGLE = $ANGLE). The SOURCE item lists the numeric code used to identify the data source.
In the coverage's lwpnt.ref INFO file the SOURCE item lists the numeric code used to identify the data source. The scale item lists the scale of the source map. (This value is the denominator of the proportional fraction that identifies the scale of the map that was digitized or scanned to produce the digital map.) The AUTHORS item lists the author(s) or compiler(s) of source map entered as last name, first name or initial, and middle initial. The YEAR item lists the source (map) publication date.
