Included in the southern part of the quadrangle is the northern part of the Peninsular Ranges Province and the northeastern part of the oil-producing Los Angeles basin. The northern part of the quadrangle includes the southern part of the Mojave Desert Province. Pre-Quaternary rocks within the San Bernardino quadrangle consist of three extensive, well-defined basement rock assemblages, the San Gabriel Mountains, San Bernardino Mountains, and the Peninsular Ranges assemblages, and a fourth assemblage restricted to a narrow block bounded by the active San Andreas Fault and the Mill Creek Fault. Each of these basement rock assemblages is characterized by a relatively unique suite of rocks that was amalgamated by the end of the Cretaceous and (or) early Cenozoic. Some Tertiary sedimentary and volcanic rocks are unique to specific assemblages, and some overlap adjacent assemblages. A few Miocene and Pliocene units cross the boundaries of adjacent assemblages, but are dominant in only one. Tectonic events directly and indirectly related to the San Andreas Fault system have partly dismembered the basement rocks during the Neogene, forming the modern-day physiographic provinces. Rocks of the four basement rock assemblages are divisible into an older suite of Late Cretaceous and older rocks and a younger suite of post-Late Cretaceous rocks. The age span of the older suite varies considerably from assemblage to assemblage, and the point in time that separates the two suites varies slightly. In the Peninsular Ranges, the older rocks were formed from the Paleozoic to the end of Late Cretaceous plutonism, and in the Transverse Ranges over a longer period of time extending from the Proterozoic to metamorphism at the end of the Cretaceous. Within the Peninsular Ranges a profound diachronous unconformity marks the pre-Late Cretaceous-post-Late Cretaceous subdivision, but within the Transverse Ranges the division appears to be slightly younger, perhaps coinciding with the end of the Cretaceous or extending into the early Cenozoic. Initial docking of Peninsular Ranges rocks with Transverse Ranges rocks appears to have occurred at the terminus of plutonism within the Peninsular Ranges. During the Paleogene there was apparently discontinuous but widespread deposition on the basement rocks and little tectonic disruption of the amalgamated older rocks. Dismemberment of these Paleogene and older rocks by strike-slip, thrust, and reverse faulting began in the Neogene and is ongoing. The Peninsular Ranges basement rock assemblage is made up of the Peninsular Ranges batholith and a variety of metasedimentary rocks. Most of the plutonic rocks of the batholith are granodiorite and tonalite in composition; primary foliation is common, mainly in the eastern part. Tertiary sedimentary rocks of the Los Angeles Basin crop out in the Puente and San Jose Hills along with the spatially associated Glendora Volcanics; both units span the boundary between the Peninsular Ranges and San Gabriel Mountains basement rock assemblages. The San Gabriel Mountains basement rock assemblage includes two discrete areas, the high standing San Gabriel Mountains and the relatively low San Bernardino basin east of the San Jacinto Fault. The basement rock assemblage is characterized by a unique suite of rocks that include anorthosite, Proterozoic and Paleozoic gneiss and schist, the Triassic Mount Lowe intrusive suite, extensive deformed and undeformed Cretaceous granitic rocks, the Pelona Schist, and Oligocene granitic rocks. Internal structure of the assemblage includes the Vincent Thrust Fault, at least two old, abandonded segments of the San Andreas Fault system, and extensive areas of well-developed to pervasively mylonitized rocks. The main body of the San Gabriel Mountains is bounded on the north by the San Andreas Fault and on the south by the Sierra Madre-Cucamonga Fault Zone. East of the San Jacinto Fault, the San Bernardino basin is an asymmetric pull-apart basin bounded by the San Andreas Fault on the east, and underlain by many of the same rock units that characterize the San Gabriel Mountains. Cretaceous and older rocks of the San Gabriel Mountains basement rock assemblage are divided into two structurally and lithologically distinct groups by the Vincent Thrust Fault, a regional, low-angle thrust fault that predates intrusion of Oligocene granitic rocks. The Vincent Thrust separates the Mesozoic Pelona Schist in its lower plate from highly deformed gneiss, schist, and granitic rocks in the upper plate. The fault, along with its far-offset, dismembered analogs in the Orocopia and Chocolate Mountains east of the Salton Sea, may underlie much of southern California. Crystalline rocks between the Mill Creek Fault and the main trace of the San Andreas Fault Zone range from highly deformed gneiss of unknown age to relatively undeformed Mesozoic biotite-hornblende diorite. They are overlain by Miocene sedimentary rocks and cut by the Wilson Creek Fault, that is considered to be an older segment of the San Andreas Fault system. Crystalline rocks of this basement assemblage are similar to rocks in the Little San Bernardino Mountains to the southeast, and appear to have been displaced about 50 km by the Wilson Creek and Mill Creek Faults. About 80 to 85 percent of the San Bernardino Mountains bedrock assemblage in the quadrangle is Mesozoic granitic rocks, and the rest, highly metamorphosed and deformed Late Proterozoic and Paleozoic metasedimentary rocks. There is a pronounced gradient from east to west, and to a slightly lesser degree from south to north, in the magnitude of both deformation and metamorphism of the Late Proterozoic and Paleozoic metasedimentary rocks. In addition to the east to west gradient of increasing metamorphism and deformation, east of the quadrangle there appears to be a sharp break between highly deformed and relatively undeformed Late Proterozoic and Paleozoic rocks. Late Proterozoic and Paleozoic units comprise a thick sequence of metasedimentary rocks generally consisting of a lower quartzitic sequence and an upper carbonate rock sequence. The entire lower quartzitic part is Late Proterozoic and Early Cambrian, and includes the Stirling Quartzite, Wood Canyon Formation and Zabriskie Quartzite; the upper carbonate rock sequence includes the Cambrian Carrara and Bonanza King Formations, the Devonian Sultan Limestone, the Mississippian Monte Cristo Limestone, and the Pennsylvanian Bird Spring Formation. Mesozoic intrusive rocks in the San Bernardino Mountains and southern Mojave Desert include numerous Triassic and Jurassic plutons. The Triassic rocks are relatively alkalic and quartz deficient, and contrast with the voluminous, quartz-rich, calc-alkalic Cretaceous granitic rocks, which make up the largest part of the San Bernardino Mountains assemblage. The voluminous tonalitic rocks in the San Gabriel Mountains and Peninsular Ranges assemblages are essentially absent in the western San Bernardino Mountains. Many areas of dominantly Cretaceous granitic rocks are mapped as Mesozoic mixed-rock units, because they are extremely heterogeneous, and include large components of older rocks. The relatively young, active San Andreas Fault system is by far the dominant structure in the San Bernardino quadrangle. Based on offsets of many of the rock units found in the San Bernardino quadrangle, different amounts of lateral displacement have been proposed for the San Andreas Fault system within and south of the Transverse Ranges. The Neogene evolution of the Transverse Ranges Province, and its relationship to the San Andreas Fault system in particular, are complicated by several abandonded segments and the shifting locus of the fault during the late Cenozoic. Most recent structural interpretations require relatively large rotations within the Transverse Ranges Province. Other active faults in the quadrangle include the San Jacinto Fault and the reverse faults bounding and within the Transverse Ranges. Older faults considered to be abandoned segments of the San Andreas Fault system include the San Gabriel Fault, Punchbowl Fault, Mission Creek Fault, and Wilson Creek Fault. The Vincent Thrust and Squaw Peak Fault are both older faults, the Vincent probably of late Mesozoic to early Tertiary age. Purpose: The data set for the San Bernardino 30'x60' 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 Geological Survey. The San Bernardino 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 San Bernardino quadrangle database has been prepared in cooperation with the National Forest Service, as part of an ongoing project to provide the San Bernardino National Forest with a geologic map base for use in managing National Forest resources and in developing interpretive materials. Supplemental_Information: The contents of this report consist of the following: 1. Geologic map database 2. Plot files for five sheets: Sheet 1 Geologic map Sheet 2 Correlation of Map Units Sheet 3 List of map units Sheet 4 Fault map Sheet 5 Three figures, including index map, physiographic provinces map, and sources of data 3. A pamphlet containing: a. A detailed Description of Map Units b. A discussion of the regional geologic framework c. Photographs of many rock units and geologic features Map nomenclature: 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. Map plot: Some contacts are very poorly located or are gradational over a very wide interval. Many of these contacts would normally be shown as scratch contacts, but at 1:100,000 scale lead to unclear map relationships. For the purposes of clarity, these scratch contacts are drawn on the map plot with a short dashed line. Dune crests within units Qoed3 and Qyed1 are mapped and recorded in the database, but are omitted from the geologic map plot file, because they obscure unit contacts. Dikes making up unit Kg are mapped and recorded in the database, but are omitted from the geologic map plot file because they are too concentrated and plot as a mass of indistinguishable lines. Intra-unit grain-size boundaries within generic Quaternary units are recorded in the database, but are in most cases poorly defined and poorly located, because the contacts are anastamosing and gradational. They also are omitted from the geologic map plot file.

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 most 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. Use of this digital geologic map should not violate the spatial resolution of the data. The San Bernardino 30' x 60' database was compiled from many sources including: (1) 1:62,500 reconnaisance mapping, (2) mapping from 1:24,000 USGS Open-File releases, (3) unpublished 1:24,000 mapping (4) Quaternary mapping from interpretation of 1:24,000 aerial photography, and (5) detailed 1:9,600 and 1:12,000 mapping from California Geological Survey Open-File releases. See Sheet 5, figure 3 for detailed sources of mapping. Any enlargement beyond the spatial resolution of the original geologic source data violates the spatial resolution of the data. Similarly, the digital topographic base data are derived from the U.S. Geological Survey, 1:100,000-scale San Bernardino 30' x 60' Digital Line Graphs (DLGs); any enlargement beyond this scale may be misleading. Where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution data. No part of the database is intended to serve for site-specific studies. Examination of a plot of the geologic map (Sheet 1) indicates detail in some areas that is far to fine to show well at 1:100,000 scale. This detail is purposely maintained to draw attention to areas where detailed information, compiled from large-scale maps is available. This detail may be viewed by on-screen examination of the digital map coverage or by plotting selected areas at larger scales. However, any enlargement beyond the spatial resolution of the original geologic source data violates the spatial resolution of the data.

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 1:100,000-scale geologic maps produced by the project. Geologic lines and points on 1:100,000 scale geologic maps are judged to meet SCAMP's internal map-accuracy standards if they are located to within +/-50 meters, relative to topographic or cultural features on the base map. On any derivative geologic-map plot, line data for faults 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. All non-fault contacts are represented by solid lines, and represent the same accuracy standards as their fault counterparts. The few non-fault dashed lines on the map represent very poorly located or highly gradational contacts, and are not as accurately located as their fault conterparts. There is no cartographic device for conveying 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 (UTM 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 San Bernardino 30'x 60' 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. In several areas, map data have been compiled from other sources (see Sheet 5, figure 3). Much but not all of this compiled work was field checked and is considered to represent the current state of knowledge in the respective areas. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The maximum transformation RMS error acceptable for 30' x 60' quadrangle transformation and data input from constituent 7.5' quadrangles and unpublished mapping is 0.003 (7.6 meters). Horizontal positional accuracy was checked by visual comparison of hard-copy plots with base-stable source data.

Minor alterations and additions to lines and polygons. Several unit names changed to conform to the most current usage and to names used in surrounding areas of San Bernardino 30' X 60' quadrangle. Process_Step: Process_Description: The San Bernardino 30'x60' quadrangle was compiled from both published and unpublished data. Compilation and integration of published sources were accomplished by initial inspection of the data, comparison to aerial photography of the area, and updating of those data either directly onscreen or by digitizing the updated data from base-stable media on which the updated data had been drawn. In the course of the compilation, due to the varied detail of data sources, some units from these sources were combined to form composite units, and in some cases unit names were changed to conform to the most current usage or more recent geologic mapping. These changes and combining of units are noted and discussed in the Description of Map Units. Geographic Information System (GIS) ArcInfo software developed by Environmental Systems Research Institute, Inc., (ESRI) v.8.1 on a SunOS, 5.8, sun4du UNIX system were used to process the work.

In addition to the customary software-defined attributes in each feature attribute table, user-defined attributes are included that allow the user access to more detailed geologic information including unit name, grain size where applicable, and rock assemblage. Two lookup tables are included: rockunit_color.lut (rockunit color assignment) and rockunit_pattern.lut (rockunit pattern assignment).
