With a compilation scale of 1:24,000 (one inch on the map to 2,000 feet on the ground), the map depicts the distribution of bedrock units, surficial deposits, and associated deformation adjacent to and south of the Arroyo Parida fault and in the southern Ojai Valley east of the Ventura River. This new compilation, combined with a recently published geologic map of the Santa Barbara coastal plain (U.S. Geological Survey Scientific Investigations Map 3001), completes a 69-km-long east-west mapping transect from Goleta to Ojai by the U.S. Geological Survey. These two contiguous geologic maps provide new insights and constraints on Neogene-through- Quaternary tectonic deformation and consequent landscape change, including geohazards in the urbanized southern flank of the Santa Ynez Mountains. A principal aim of the new mapping and associated fault-kinematic measurements is to document and constrain the nature of transpressional strain transfer between various regional, potentially seismogenic faults. In the accompanying pamphlet, surficial and bedrock map units are described in detail as well as a summary of the structural and fault-kinematic framework of the map area. New biostratigraphic and biochronologic data based on microfossil identifications are presented in expanded unit descriptions of the marine Neogene Monterey and Sisquoc Formations. Site-specific fault kinematic observations are embedded in the digital map database. This compilation provides a uniform geologic digital geodatabase and map plot files that can be used for visualization, analysis, and interpretation of the area’s geology, geologic hazards, and natural resources. Purpose: To update the interpretation of geologic mapping and to achieve a uniform regional geologic database. Additionally, to provide a geologic map for the public and geoscience community to aid in assessments and mitigation of geologic hazards in the map region and to provide sufficient geologic information for land-use and land-management decisions.

The present geologic compilation of the southern parts of the White Ledge Peak and Matilija 7.5’ quadrangles comprises new, original mapping based mainly on field and aerial-photo geologic observations and interpretations. Most of the geologic mapping and interpretations presented in this report are based on observations made on the ground surface or in shallow surface excavations. Lead author Minor conducted all of the geologic mapping and made most of the geologic interpretations in the map area. Minor also made all of the fault kinematic observations and measurements in the map area. T.R. Brandt assisted in the design and editing of the GIS database and performed database integration. Native_Data_Set_Environment: Windows_7, Intel ArcInfo version 9.3.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Data were entered and checked by the geologist that made the field 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 or digital 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 closure, and other errors by the lead author and by the GIS technician(s) that created the digital database. Automated (ArcInfo) 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. Check plots of the map were reviewed by at least one other geologist for consistency with basic geologic principles and general conformity to USGS mapping standards. Completeness_Report: Data are complete: no features that could be accurately represented at the compilation scale of 1:24,000 were eliminated or generalized. The smallest area represented is approximately 110 square meters. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Lines were primarily mapped by one of the following methods: (1) photo-interpretation and annotation of ~1:24,000-scale color (1999, 2001) and ~1:39,000-scale color infrared National Aerial Photography Program (https://lta.cr.usgs.gov/NAPP) (2002) aerial photographs; or (2) annotation of 1:24,000-scale topographic base maps. All point observation locations were determined in the field using hand-held GPS receivers with horizontal positional accuracy ranging from about 5 to 10 m. Map data were digitized by one of the following methods: (1) heads-up screen digitization of line data mapped on aerial photographs using rectified and georeferenced digital aerial photo imagery with ground resolution of 1 meter; and (2) heads-up screen digitization of mapped data using raster images of topographic base maps to an estimated horizontal accuracy of about 10 m. Most digitized positions on the map are estimated to have better than 20 m horizontal accuracy. There is no elevation data in the database. Accuracy of these digital data indirectly depends on accuracy of the base maps on which the original source geologic maps were compiled. These base maps were made by the U.S. Geological Survey, which routinely checks them for compliance with the National Map Accuracy Standards.

In the wlmaslip.pat INFO file, the PTTYPE item lists the type of point symbol (for example, strike and dip of inclined bedding). The SYMBOL 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 STRIKE value also specifies the dip direction, where the dip direction is 90 degrees clockwise relative to the STRIKE.

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 RAKE item contains the rake of lineation. RAKE is the angle, measured in the fault slip plane, subtended by the slip vector (lineation) and the strike direction of the slip plane. The actual rake value recorded in the map database ranges from 0 to 360 degrees, depending on both the rake angle and the fault slip sense. The SLIPSENS item contains the fault slip sense. "Fault slip sense" refers to the sense or direction of movement of the block of rock or material on one side of a fault relative to the block on the other side. Fault slip that includes a component of normal movement (i.e., downward hanging-wall block motion) has rake values ranging from 0 to 180 degrees, whereas slip that includes a reverse component of movement (i.e., upward hanging-wall block motion) has rake values ranging from 180 to 360 degrees. Fault movement that includes a component of sinistral strike slip has rake values that range from 270 to 360 degrees (where accompanied by reverse slip) and from 0 to 90 degrees (where accompanied by normal slip). Fault movement that includes a component of dextral strike slip has rake values that range from 90 to 180 degrees (where accompanied by normal slip) and from 180 to 270 degrees (where accompanied by reverse slip). Pure sinistral strike-slip, normal-slip, dextral strike-slip, and reverse-slip faults have rake values of 0 (=360), 90, 180, and 270 degrees, respectively. SLIPSENS is a two-letter alpha descriptor that describes the fault slip sense determined at the same location along the fault trace where the associated slip lineation rake was measured. A fault may have one of four possible primary slip senses (reverse [R], dextral [D], normal [N], and sinistral [S]), each of which may have two possible secondary slip senses depending on the slip-lineation rake value, for a total of twelve possible slip-sense letter combinations. Faults with measured lineation rake angles greater than 45 degrees have either reverse or normal primary slip senses, whereas those with rake angles less than 45 degrees have either sinistral or dextral strike-slip primary slip senses. Faults with lineation rake angles within 15 degrees of the slip plane's dip and strike have pure normal or reverse and pure dextral or sinistral slip senses, respectively; in such cases no secondary slip sense letter descriptor is used. The twelve possible slip-sense two-letter descriptor combinations are as follows, with the first letter of each combination indicating the primary slip sense: S, SN, NS, N, ND, DN, D, DR, RD, R, RS, and SR. The RELAGE item contains the relative age of multiple sets of slip lineations or intersecting faults. RELAGE is a numerical code that indicates the relative age (based mostly on cross-cutting relations observed in the field) of: (1) multiple sets of slip lineations measured on a single fault plane, and (2) intersecting faults. There are three possible relative age values (1, 2, 3), with 1-older, 2-intermediate or younger, and 3-youngest (0-not applicable). The CERTCODE and SENCERT items contain numerical codes and corresponding alpha descriptors, respectively, that indicate the certainty of the slip-sense determination. There are three possible slip-sense certainty codes and descriptors, as follows: 1-certain, 2-probable, 3-questionable (0-not applicable).SEPAR is the amount of separation (in meters) measured across the fault at or near the fault observation point. SEPTYPE is an alpha descriptor that indicates the type of separation measured, with D-dip separation and S-strike separation. The SOURCE item lists the numeric code used to identify the data source. In the wlmaslip.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.

In the wlmamslip.pat INFO file, the PTTYPE item lists the type of point symbol (for example, strike and dip of inclined bedding). The SYMBOL 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 STRIKE value also specifies the dip direction, where the dip direction is 90 degrees clockwise relative to the STRIKE. The DIP item contains the dip of bedding as well as plunge angles, where applicable. This value is an angle measured (in degrees from 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 RAKE item contains the rake of lineation. RAKE is the angle, measured in the fault slip plane, subtended by the slip vector (lineation) and the strike direction of the slip plane. The actual rake value recorded in the map database ranges from 0 to 360 degrees, depending on both the rake angle and the fault slip sense. The SLIPSENS item contains the fault slip sense. "Fault slip sense" refers to the sense or direction of movement of the block of rock or material on one side of a fault relative to the block on the other side. Fault slip that includes a component of normal movement (i.e., downward hanging-wall block motion) has rake values ranging from 0 to 180 degrees, whereas slip that includes a reverse component of movement (i.e., upward hanging-wall block motion) has rake values ranging from 180 to 360 degrees. Fault movement that includes a component of sinistral strike slip has rake values that range from 270 to 360 degrees (where accompanied by reverse slip) and from 0 to 90 degrees (where accompanied by normal slip). Fault movement that includes a component of dextral strike slip has rake values that range from 90 to 180 degrees (where accompanied by normal slip) and from 180 to 270 degrees (where accompanied by reverse slip). Pure sinistral strike-slip, normal-slip, dextral strike-slip, and reverse-slip faults have rake values of 0 (=360), 90, 180, and 270 degrees, respectively. SLIPSENS is a two-letter alpha descriptor that describes the fault slip sense determined at the same location along the fault trace where the associated slip lineation rake was measured. A fault may have one of four possible primary slip senses (reverse [R], dextral [D], normal [N], and sinistral [S]), each of which may have two possible secondary slip senses depending on the slip-lineation rake value, for a total of twelve possible slip-sense letter combinations. Faults with measured lineation rake angles greater than 45 degrees have either reverse or normal primary slip senses, whereas those with rake angles less than 45 degrees have either sinistral or dextral strike-slip primary slip senses. Faults with lineation rake angles within 15 degrees of the slip plane's dip and strike have pure normal or reverse and pure dextral or sinistral slip senses, respectively; in such cases no secondary slip sense letter descriptor is used. The twelve possible slip-sense two-letter descriptor combinations are as follows, with the first letter of each combination indicating the primary slip sense: S, SN, NS, N, ND, DN, D, DR, RD, R, RS, and SR. The RELAGE item contains the relative age of multiple sets of slip lineations or intersecting faults. RELAGE is a numerical code that indicates the relative age (based mostly on cross-cutting relations observed in the field) of: (1) multiple sets of slip lineations measured on a single fault plane, and (2) intersecting faults. There are three possible relative age values (1, 2, 3), with 1-older, 2-intermediate or younger, and 3-youngest (0-not applicable). The CERTCODE and SENCERT items contain numerical codes and corresponding alpha descriptors, respectively, that indicate the certainty of the slip-sense determination. There are three possible slip-sense certainty codes and descriptors, as follows: 1-certain, 2-probable, 3-questionable (0-not applicable).SEPAR is the amount of separation (in meters) measured across the fault at or near the fault observation point. SEPTYPE is an alpha descriptor that indicates the type of separation measured, with D-dip separation and S-strike separation. The SOURCE item lists the numeric code used to identify the data source. >COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME > 1 AREA 8 18 F 5 > 9 PERIMETER 8 18 F 5 > 17 WLMAMSLIP# 4 5 B - > 21 WLMAMSLIP-ID 4 5 B - > 25 PTTYPE 100 100 C - > 125 SYMBOL 2 5 B - > 127 STRIKE 2 5 B - > 129 DIP 2 5 B - > 131 BEARING 2 5 B - > 133 RAKE 2 5 B - > 135 SLIPSENS 4 4 C - > 139 RELAGE 2 5 B - > 141 CERTCODE 2 5 B - > 143 SENCERT 20 20 C - > 163 SEPAR 4 12 F 3 > 167 SEPTYPE 3 3 C - > 170 SOURCE 2 5 B - > >WLMAMSLIP.REF: > >COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME > 1 SOURCE 4 4 I - > 5 SCALE 8 8 I - > 13 AUTHORS 200 200 C - > 213 YEAR 4 4 I - > 217 REFERENCE 250 250 C - wlmadec coverage: Contains points recording site-specific observations and measurements of fold axis plunge arrows In the wlmadec.pat INFO file, the PTTYPE item lists the type of point symbol (for example, strike and dip of inclined bedding). The SYMBOL 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 as well as bearing of lineation or trend of fold axis, where applicable. Strike is an azimuthal angle. Measured in degrees from 0 to 360 in a clockwise direction from North, the STRIKE value also specifies the dip direction, where the dip direction is 90 degrees clockwise relative to the STRIKE. The DIP item contains the dip of bedding as well as plunge angles, where applicable. This value is an angle measured (in degrees from 0 to 90) down from the horizontal; thus a horizontal dip is 0 degrees and a vertical dip is 90 degrees.
