Publisher: United States Geological Survey Online_Linkage: http://pubs.usgs.gov/sim/2005/2896/ Description: Abstract: Geologic mapping, in support of the USGS Middle Rio Grande Basin Geologic Mapping Project, shows the spatial distribution of artificial-fill, alluvial, and colluvial deposits, Santa Fe Group, as well as lava flows and related sediments of the Cerros del Rio volcanic field. These deposits are in the southern part of the Espanola basin west of central Santa Fe, N. Mex. Artificial-fill deposits are mapped chiefly at and near segments of roads, commercial developments, and active and inactive landfills. Alluvial deposits are mapped in stream channels, below low terraces, and on hill slopes. These deposits include alluvium in stream channels and below low terraces, gravelly stream alluvium, and sheetwash deposits. Undivided alluvial and colluvial deposits consist of fan alluvium and debris-flow deposits. Colluvial deposits were mapped on hill slopes and include undivided colluvial deposits, younger debris-flow deposits, and older debris-flow deposits. Lava flows and related sediments of the Cerros del Rio volcanic field were mapped along the western boundary of the map area. These deposits include six lava flows of basaltic to andesitic composition, basaltic alluvium, basaltic tephra, as well as undivided basaltic tephra and Ancha Formation. The Santa Fe Group is locally well exposed in stream cuts mostly in the northern and eastern parts of the map area. Deposits in the group include the Ancha Formation, upper coarse unit of the Tesuque Formation, and lower unit of the Tesuque Formation. Most faults in the map area cut Miocene sediments of the lower unit of the Tesuque Formation. Some faults cut sediments of the Ancha Formation. Displaced sediments in the Ancha Formation are of Pliocene age and are possibly as young as early Pleistocene (about 1.5-1.8 million years old). The mapped surficial deposits (post-Santa Fe Group)are known or estimated to be at least 1 m thick. The Santa Fe Group and most of the surficial deposits are poorly exposed. Thin (<50 cm), discontinuous sheetwash (unit Qsw) locally mantles gently sloping map units as old and older than younger terrace alluvium (unit Qty). We did not map deposits that are (1) of limited extent (less than about 24 m wide), (2) exposed in steep cuts, and (3) fill material (unit af) that was not observed on aerial photographs. The distribution of map units is based primarily on interpretation of 1:24,000-scale, color aerial photographs taken in 1990 and 1:40,000-scale, black-and-white aerial photographs taken in 1996. Most of the contacts on the map were transferred from the aerial photographs using a stereoplotter. The satellite image was obtained from processed Landsat 7 satellite imagery (band 7-4-2 and band 8) created from two Landsat 7 scenes acquired during October 1999. One of the versions of the Agua Fria quadrangle geologic map has screened shaded relief generated from 10-m data in the National Elevation Dataset. These data were collected on 10-m spacings. Sun illumination is from the northwest at 45¡ above the horizon. Metric units are used in this report, except for measurements in the Yates La Mesa No. 2 drill hole, which were recorded in feet. Purpose: This map provides geologic information for land-use decisions.

Native_Data_Set_Environment: Windows_XP, Intel ARCINFO version 9.1 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 dataset 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. This map has been thoroughly reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature. 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 U.S. Geological Survey mapping standards. Completeness_Report: Data are complete. No features that could be accurately represented at a scale of 1:24,000 were eliminated or generalized. The smallest area represented is approximately 20 square meters. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The distribution of map units is based primarily on interpretation of 1:24,000-scale, color aerial photographs taken in 1990, and 1:40,000-scale, black- and-white aerial photographs taken in 1996. Most of the contacts on this map were transferred from the aerial photographs using a stereoplotter. The location of the Yates La Mesa No. 2 drill hole is based on coordinates reported by Bruce A. Black (Black Oil, Inc., written commun., 1985). Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Aldern, J.L.

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. aguageo 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 aguageo.ref file. The LABEL item indicates the rock unit label (abbreviation) used to label unit on map. The DESC item defines the 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. In the aguageo.aat INFO file, the LINECODE item provides a numeric code used to identify type of linear feature. Linecodes less than 100 are used for contacts and boundaries, which are described in the aguageo.con file. Linecodes greater than 100 are used for structures that are described in the aguageo.str file. The NAME item lists the name given to structural feature. The SOURCE item lists the numeric code used to identify the data source for the linear feature. The SYMBOL item lists the line symbol number used by ArcInfo to plot the line (symbol numbers refer to the geol_sfo.lin lineset). Complete references for the sources are listed in the aguageo.ref file. Related look-up table files are aguageo.con, aguageo.str, and aguageo.ref. In the aguageo.con INFO file, the LINECODE item indicates the numeric code (a value less than 100) used to identify type of contact or boundary. The SYMBOL item lists the line symbol number used by ArcInfo to plot the line (symbol numbers refer to the geol_sfo.lin lineset included with the dataset). The TYPE item lists the major type of line (for example, contact, State boundaries, lines of latitude and longitude used for neatlines). The MODIFIER item lists the line type modifier (that is, approximate, concealed, or gradational). No entry implies 'known.' The CERTAINTY item lists the degree of certainty of contact or boundary (that is, inferred or uncertain). No entry implies 'certain.' The DESC item lists the written description or explanation of the contact or boundary. In the aguageo.str INFO file, the LINECODE item indicates the numeric code (a value greater than 100) used to identify type of structure. The SYMBOL item lists the line symbol number used by ArcInfo to plot the line (symbol numbers refer to the geol_sfo.lin lineset 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).
