Most of the quadrangle consists of a dissected plateau that was formed on the resistant caprock of the Bandelier Tuff, which was erupted from the Valles caldera approximately 1 to 2 million years ago. Within the canyons of the east-flowing streams that eroded this volcanic tableland, Miocene and Pliocene fluvial deposits of the Puye Formation and Santa Fe Group are exposed beneath the Bandelier Tuff. These older units preserve sand and gravel that were deposited by streams and debris flows flowing from source areas located mostly north and northeast of the Puye quadrangle. The landscape of the southeastern part of the quadrangle is dominated by the valley of the modern Rio Grande, and by remnants of piedmont-slope and river-terrace deposits that formed during various stages of incision of the Rio Grande drainage on the landscape. Landslide deposits are common along the steep canyon walls where broad tracts of the massive caprock units have slumped toward the canyons on zones of weakness in underlying strata, particularly on silt/clay-rich lacustrine beds within the Puye Formation. Purpose: Geology of the Puye quadrangle was mapped as part of the USGS Middle Rio Grande Basin project of the late 1990's to explore the geologic framework of water resources in the region. Mapping was conducted in part on lands of the Santa Clara Indian Reservation and the San Ildefonso Indian Reservation, with the permission of the Indian Nations. Supplemental_Information: datasets included in this publication: puye_geol(.shp) puye_faults(.shp) puye_pnts(.shp) puye_base.tif(tfw) Portrayal of geologic map units is consistent with the 1:24,000 scale of the map; areas of the map classified as one unit locally include areas of other rock units too small to depict separately. The descriptions of the rock materials and physical properties are representative of the range of characteristics within the map unit in this quadrangle, but specific characteristics vary from place to place. Information contained in this database and depicted on the map may provide useful guides to the engineering and resource characteristics of the units, but is typically too generalized for evaluating uses or hazards of specific sites.

Native_Data_Set_Environment: SunOS, 5.6, sun4m UNIX ARC/INFO version 7.1.2 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: These data were checked by the geologist who made the original field observations. Attributes of this geospatial data set consist of text identifiers and numeric codes that indicate the identity and type of the geologic feature; these codes determine the display characteristics of the data in terms of color and symbology. Accuracy was established by comparison of check plots to the geologist's original map compilation. Machine-generated lists of unique attribute values were checked for spelling errors or inconsistencies. In addition, the report has been reviewed for technical content, as well as for conformity with USGS standards for editorial format and stratigraphic nomenclature. Logical_Consistency_Report: Map elements were visually inspected by the geologist and by the GIS technician(s) that created the database coverages to detect undershoots, overshoots, duplicate features, polygon closure, and similar errors. Automated routines were invoked to detect label and attribute errors, sliver polygons, dangling arcs, intersection errors, and projection information. Check plots of the map were reviewed by at least two other geologists for consistency with basic geologic principles and for general conformity to USGS mapping standards. Completeness_Report: Data are complete; no features that could be accurately represented at map scale were eliminated or generalized. All geospatial database elements are attributed. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Lines on the map were positioned by photointerpretation from 1:40,000-scale aerial photography and from direct observation in the field. Features were digitized by scanning the geologic compilation and vectorizing; with geodetic rectification, features on the map are estimated to be accurately located within about 10 m horizontal dimension.

Locations and orientations were checked by the geologist on draft plots Process_Date: 1999 Process_Step: Process_Description: Draft check plots of map elements, along with text, correlation diagram, and descriptions of symbols were reviewed by peers for technical accuracy and USGS mapping standards. Revisions were made to the database to reflect necessary revisions. Process_Date: 2000 Process_Step: Process_Description: chief (representing the geologist); draft metadata were reviewed in the Team and revised as necessary. Database elements were checked and reviewed within the team for topological correctness. Process_Date: 2001 Process_Step: Process_Description: Digital database files, text files, metadata, and related information were reviewed by USGS Central Publications Group and revised as necessary. CPG prepared layout of map sheet elements, adjusted colors and patterns, imported standard USGS symbols and marginalia and composed the map sheet for print-on-demand distribution. Approval of the USGS Director to publish was obtained. Final geospatial database files were prepared for web distribution, the map sheet image was converted to PDF for the web- browse graphic, and all relevant items were posted on the USGS map server for public access Process_Date: 2003 Spatial_Data_Organization_Information: Direct_Spatial_Reference_Method: Vector Point_and_Vector_Object_Information: SDTS_Terms_Description: SDTS_Point_and_Vector_Object_Type: Point Point_and_Vector_Object_Count: 948 SDTS_Terms_Description: SDTS_Point_and_Vector_Object_Type: String Point_and_Vector_Object_Count: 2779 SDTS_Terms_Description: SDTS_Point_and_Vector_Object_Type: GT-polygon composed of chains Point_and_Vector_Object_Count: 943 Spatial_Reference_Information: Horizontal_Coordinate_System_Definition: Planar: Grid_Coordinate_System: Grid_Coordinate_System_Name: Universal Transverse Mercator Universal_Transverse_Mercator: UTM_Zone_Number: 13 Transverse_Mercator: Scale_Factor_at_Central_Meridian: 0.9996 Longitude_of_Central_Meridian: -106.1875 Latitude_of_Projection_Origin: 35.875 False_Easting: 0.00 False_Northing: 0.00 Planar_Coordinate_Information: Planar_Coordinate_Encoding_Method: coordinate pair Coordinate_Representation: Abscissa_Resolution: 10 Ordinate_Resolution: 10 Planar_Distance_Units: Meters Geodetic_Model: Horizontal_Datum_Name: North American Datum of 1927 Ellipsoid_Name: Clarke 1866 Semi-major_Axis: 6378206.4 Denominator_of_Flattening_Ratio: 294.98 Entity_and_Attribute_Information: Overview_Description: Entity_and_Attribute_Overview: DATASET NAMES: PUYE_GEOL PUYE_FAULTS PUYE_PNTS COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME INDEXED? 1 AREA 4 12 F 3 - 5 PERIMETER 4 12 F 3 - 9 PUYE_GEOL# 4 5 B - - 13 PUYE_GEOL-ID 4 5 B - - 17 UNIT 10 10 C - - 27 SYMBOL 4 4 I - - 31 DESCRIPTION 100 100 C - - explanation of item names: UNIT - geologic unit label SYMBOL - unique number given to map unit representing color value taken from shadeset wpgcmykg.shd DESCRIPTION - brief geologic explanation of map units UNIT SYMBOL DESCRIPTION ---- ------ ----------- QToa 23 Alluvial deposit (early Pleistocene or late Pliocene) QTtp 72 Piedmont alluvium (early Pleistocene(?) and late Pliocene) Qaf 61 Tributary alluvial fan deposit (Holocene to late Pleistocene) Qafp 60 Piedmont alluvial fan deposit (Holocene to late Pleistocene(?))
