Publisher: United States Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2012/1041 Description: Abstract: This map covers the Big Costilla Peak, New Mex.-Colo. quadrangle and adjacent parts of three other 7.5 minute quadrangles: Amalia, New Mex.-Colo., Latir Peak, New Mex., and Comanche Point, New Mex. The study area is in the southwesternmost part of that segment of the Sangre de Cristo Mountains that is known as the Culebra Range; the Taos Range segment lies to the southwest of Costilla Creek and its tributary, Comanche Creek. The map area extends over all but the northernmost part of the Big Costilla horst, a late Cenozoic uplift of Proterozoic (1.7- and lesser 1.4-Ga) rocks that is largely surrounded by down-faulted middle to late Cenozoic (about 40 to about 1 Ma) rocks exposed at significantly lower elevations. This horst is bounded on the northwest side by the San Pedro horst and Culebra graben, on the northeast and east sides by the Devils Park graben, and on the southwest side by the about 30-to-about 25-Ma Latir volcanic field. The area of this volcanic field, at the north end of the Taos Range, has undergone significantly greater extension than the area to the north of Costilla Creek. The horsts and grabens discussed above are all peripheral structures on the eastern flank of the San Luis basin, which is the axial part of the about 26 Ma- to-present Rio Grande rift at the latitude of the map. The Raton Basin lies to the east of the Culebra segment of the Sangre de Cristo Mountains. This foreland basin formed during, and is related to, the original uplift of the Sangre de Cristo Mountains, which was driven by tectonic contraction of the Laramide (about 70 to about 40 Ma) orogeny. Renewed uplift and structural modification of these mountains has occurred during formation of the Rio Grande rift. Surficial deposits in the study area include alluvial, mass-movement, and glacial deposits of middle Pleistocene to Holocene age. Purpose: To provide a digital geologic map database of the four-quadrangle area that improves understanding of the regional geologic framework.

Native_Data_Set_Environment: Windows_XP, Intel ARC/INFO version 9.3.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Data were checked by the geologist that made the field observations and compilation. 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 the attribute accuracy, a color check plot was visually compared to the geologist's original compilation. Discrepancies between the digital geospatial data set 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 closure, and other errors by the authors and by the GIS technician(s) who 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 another geologist and cartographer for consistency with basic geologic principles and general conformity to USGS mapping standards. Completeness_Report: Data are preliminary. No features that could be accurately represented at a scale of 1:24,000 were eliminated or generalized. The smallest area represented is approximately 45 square meters. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Most digitized positions on the map that depict distinct contacts between rock formations in the field are estimated to be within 20 m of the actual contact on the land in most instances. Boundaries (lines) between Quaternary units (for example, terrace gravels) that correspond closely to distinct edges of landforms (for example, river terraces) are of comparable accuracy. Boundaries (lines) between some Quaternary units, such as eolian deposits and broad alluvial aprons, are approximately located within an indefinite gradational zone between them. Horizontal positional accuracy is tested by visual comparison of hard copy test plots to source maps or comparing locations of data on a computer monitor to other data layers in the same geographic area. The database contains no elevation data. 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.

DATABASE STRUCTURE - ArcInfo ==================================== This GIS database includes related look-up tables, which store detailed attribute information. This database structure is more fully described in USGS OFR 99-438. The GIS database structure used in the database includes symbol and pattern items in coverage point, polygon (PAT), and arc (AAT) attribute tables for user convenience. ArcInfo relates for each coverage are saved in a file named .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. bigcgeo coverage: Contains all contact lines and label points for each geologic polygon. In the .pat INFO file the SOURCE item provides a numeric code used to identify the data source for the rock unit. Complete references for the sources listed are listed in the bigcgeo.ref file. The LABEL item indicates the rock unit label (abbreviation) used to label unit on map. The DESC item defines formal or informal unit name. The SYMBOL item contains the shadeset symbol number used by ArcInfo to plot a filled/shaded polygon. The symbol numbers in this item refer to the wpgcmykg.shd shadeset included with the dataset.

The TYPE item lists the major type of line (for example, fault or fold-axis). The HORIZONTAL item refers to the type of horizontal fault movement (for example, left-lateral or right- lateral). No entry implies 'unknown' or no strike-slip movement. The VERTICAL item refers to the type of vertical fault movement (for example, normal). No entry implies 'unknown' or no dip-slip movement. The FOLD item refers to the type of fold (for example, anticline or syncline). The PLUNGE item refers to the type of plunge on fold (that is, horizontal, plunging, plunging in, or plunging out). The ACCURACY item refers to the line type modifier indicating degree of accuracy (that is, approximately located, concealed, gradational). No entry implies 'certain.' The CERTAINTY item lists the degree of certainty of structure (that is, inferred, uncertain). No entry implies 'certain.' The DESC item lists the written description or explanation of the structure.
