Steve Ludington Barry C. Moring Robert J. Miller Kathryn S. Flynn Paul A. Stone David R. Bedford 2005 Preliminary integrated databases for the United States - Western States: California, Nevada, Arizona, and Washington Version 1.0 vector digital data U.S. Geological Survey Open-File Report OFR 2005-1305 Reston, Virginia, USA U.S. Geological Survey http://pubs.usgs.gov/of/2005/1305 cageol_lcc These digital maps are a reformulation of previously published maps, primarily maps of states. The reformulation gives all the maps the same structure and format, allowing them to be combined into regional maps. The associated data tables have information about age and lithology of the map units, also in a standard format. Provide digital maps and databases that, because of their common structure and format, allow creation of regional maps that depict age and lithology of map units. The data is provided in decimal degrees and in Lambert Conformal Conic projection. The data is provided in both coverage and shapefile format, and includes supplemental attribute tables. No attempt was made to reconcile differences in mapping across state boundaries. en 2005 publication date Complete None planned -126.494824 -113.794483 43.802247 31.088099 -2161573.559731 -1293542.828006 4039905.581245 5265118.553717 none geology lithology geologic age maps none USA California No warranty, expressed or implied, is made regarding the accuracy or utility of this data for general or scientific purposes, nor shall the act of distribution constitute any such warranty.

Menlo Park CA 94025 USA 650.329.5371 slud@usgs.gov U.S. Geological Survey, California Geological Survey ESRI ArcCatalog 9.0.0.535 ArcInfo Coverage Map unit designations follow original compilation faithfully. Additional information about age and lithology was obtained from the paper map legend and geologic literature. All internal polygons were checked for closure. Overshoots and undershoots have been deleted or corrected as appropriate. The dataset contains all the map units and faults that were portrayed on the original printed map. Bodies of water are classified as water, and geologic units underlying them are not portrayed. The geologic map was digitized from compilations ranging in scale from 1:100,000 to 1:1,000,000, and is an accurate representation of the source maps. It is intended to be used at scales equal to or smaller than 1:500,000. Display at significantly larger scales may produce error in location of contacts or faults relative to features contained in other data sets. The state boundary arcs are based on the 1:100,000 scale USGS topographic map series digital line graphs. Many water boundaries do not correspond closely to other datasets. n/a Saucedo, G.J. Bedford, D.R. Raines, G.L. Miller, R.J. Wentworth, C.M. 2000 GIS data for the geologic map of California vector digital data DMG CD 2000-007 Sacramento, CA California Geological Survey Digitized from the 1977 Geologic Map of California by C.W. Jennings CD-ROM digital map we started from Bruce R. Johnson Unpublished Material State boundaries vector digital data 100,000 online US001 Provided linework for state boundaries Dataset copied. 2002 Adjusted the perimeter of the coverage to match a reference dataset of state boundaries derived from 1:100,000 scale digital line graphs. This allows the map to be used together with adjoining state maps referenced to the same boundary data. Replaced a section of the state boundary that follows the Colorado River with a line from 1:100,000 scale digital line graph hydrographic files. The state and international boundaries have a source of US001 in the AAT. 2004 Relabeled 8 polygons to conform to the printed map. These adjustments have a source of CA202 in the PAT. 2003 During rectification of arc errors, created 9 new polygons to conform to the printed map. These adjustments have a source of CA201 in the PAT. 2003 Nine arcs were either added or extended to conform to the printed map's polygon representation. These adjustments have a source of CA101 in the AAT. 2003 A number of faults on the printed map have small breaks that were originally coded as scratch boundaries. We concluded that these breaks were meant to imply approximate location, and so have changed the label on 281 arcs to reflect that interpretation. These adjustments have a source of CA102 in the AAT. 2003 A number of arcs were present, coded as contacts or scratch boundaries that unnecessarily divided two polygons with the same label. These arcs were eliminated and the corresponding polygons consolidated. 2003 The appropriate arcs were recoded as state and international boundaries. 2005 To prepare a uniform AAT file, the following items were added: arc-code, arc-para1, and arc-para2. The last two are not used. Arc-code was populated, using the information in the original item, and inspection of the printed map. Then the original items in the AAT were deleted (LTYPE, SEL, SYMB). 2005 To prepare a uniform PAT file, the following items were added: ORIG_LABEL, SGMC_LABEL, UNIT_LINK, SOURCE, UNIT_AGE, ROCKTYPE1, and ROCKTYPE2. ORIG_LABEL was populated from the original item (PTYPE). New unit designations for SGMC_LABEL were developed by Paul Stone, David Miller, and Steve Ludington, based on the geologic literature, personal communications, and personal knowledge. UNIT_LINK was populated with information in the accompanying attribute table CAunits, UNIT_AGE was populated with information in the accompanying attribute table CAage, and ROCKTYPE1 and ROCKTYPE2 were populated with information in the accompanying attribute table CAlith. Then the original items in the PAT were deleted (PTYPE, SEL, SYMB). 2005 Because California has such complex geology, many of the original map units contained a wide variety of lithologies and are difficult to characterize. We subdivided many of the units, grouping outcrops with common characterisitcs that allowed a coherent description. For example, the map unit SO (Silurian and Ordovician sedimentary rocks) was divided into SO1 (southeastern California - primarily dolomite and limestone), SO2 (eastern Sierra Nevada - primarily argillite and sandstone), and SO3 (eastern Klamath Mountains - primarily graywacke and phyllite). These subunits were named by simply appending an integer and placing the resulting label into SGMC_LABEL. Their geographic, lithologic, and age characteristics are recorded in the accompanying attribute tables (CAunits, CAlith, CAage). 2004 Metadata imported. withheld Metadata imported. withheld Metadata imported. withheld 20050817 Dataset copied. withheld 20071130 Vector Complete chain 52801 Label point 12239 GT-polygon composed of chains 12239 Point 37 Label point 0 String 0 Simple Arc FALSE 52795 FALSE FALSE Simple Label FALSE 12239 FALSE FALSE Simple Polygon TRUE 12239 FALSE FALSE Simple Tic FALSE 37 FALSE FALSE Annotation FALSE 0 FALSE FALSE Simple Link FALSE 0 FALSE FALSE coordinate pair 0.002048 0.002048 meters Lambert Conformal Conic 33.000000 45.000000 -100.000000 0.000000 0.000000 0.000000 North American Datum of 1927 Clarke 1866 6378206.400000 294.978698 GCS_North_American_1927 NAD_1927_Lambert_Conformal_Conic cageol_lcc96.aat Feature Class 52795 FID Internal feature number.
