Abstract:
Geologic mapping, in support of the USGS Middle Rio Grande Basin Geologic Mapping Project, shows the spatial distribution of artificial-fill, alluvial, colluvial, and eolian deposits, lava flows and related sediments of the Albuquerque volcanoes, and upper Santa Fe Group sediments. These deposits are on, beneath, and along the West Mesa (Llano de Albuquerque) just west of Albuquerque, New Mexico. Artificial fill deposits are mapped chiefly beneath and near segments of Interstate 40, in an inactive landfill (or dump) north of Interstate 40 near the eastern boundary of the map area, and in the active Cerro Colorado landfill near the southwestern corner of the map area. Alluvial deposits are mapped in stream channels, beneath treads of terraces, and on hill slopes. They include alluvium in stream channels and beneath treads of low terraces, terrace alluvium, sheetwash deposits, gravelly alluvium, and old alluvium and calcic soils of the Llano de Albuquerque. Alluvial and colluvial deposits are mapped on hill slopes. They include young alluvial-slope deposits, alluvium and colluvium, undivided, and old alluvial-slope deposits. Colluvial deposits are also mapped on hill slopes. They include colluvial deposits, undivided, as well as alluvial deposits, eolian sand, and calcic soils associated with fault scarps. Eolian deposits as well as eolian and alluvial deposits mantle gently slopping surfaces on the Llano de Albuquerque. They include active eolian sand, active and inactive eolian sand and sheetwash deposits, undivided, and inactive eolian sand and sheetwash deposits, undivided. Lava flows and related sediments of the Albuquerque volcanoes were mapped near the southeast corner of the map area. They include five young lava flows, two young cinder deposits, and old lava flows. Upper Santa Fe Group sediments are well exposed and mapped in the western part of the map area. They include a gravel unit, a pebbly sand unit, and a mud and sand unit. Undivided upper Santa Fe Group sediments were mapped in the eastern part of the map area.
Sediments and lava flows in the map area record alluvial, eolian, colluvial, and volcanic processes of the past several million years. The surficial deposits (post-Santa Fe Group sediments) on the map are known or estimated to be at least 1 m thick; most deposits are poorly exposed. Thin (< 50 cm), discontinuous deposits of eolian sand and sheetwash (Qea, Qes, and Qsw) locally are present on gently sloping map units older than the alluvium in stream channels and low terraces (Qa). These thin eolian and sheetwash deposits are not mapped, but they are widespread on the gravel unit of the upper Santa Fe Group sediments (Tg) on the eastern flank of the Llano de Albuquerque, near the eastern boundary of the map area (quadrangle). Small deposits of artificial fill (af) less than about 25 m wide are not mapped. Fractional map symbols (for example, Qsw/Qby1) are used where sheetwash deposits mantle lava flows. These fractional units are not described here; instead refer to descriptions of individual units.
Purpose: This map provides geologic information for land-use decisions.
Supplemental_Information:
The geology was mapped in 1996-1999. The primary mapping responsibilities were as follows. Shroba mapped the surficial deposits and the upper undivided unit of the Santa Fe Group sediments (Ts) in the eastern part of the map area. Schmidt and Maldonado mapped the upper Santa Fe Group sediments in the western part of the map area. Schmidt mapped north of Interstate 40, and Maldonado mapped south of Interstate 40. Thompson mapped the volcanic rocks in the northeastern part of the map area. Personius interpreted the aeromagnetic data and mapped the faults on the Llano de Albuquerque and along the eastern boundary of the map area. Brandt create the GIS database and performed the digital GIS cartography.

Data_Set_Credit: This report was improved greatly by helpful reviews by David S. Fullerton and Daniel R. Muhs of the U.S Geological Survey. Tien Grauch of the U.S. Geological Survey assisted with interpretation of some of the aeromagnetic data. David A. Sawyer of the U.S. Geological Survey determined the location of Westland Development Corporation No. 1-Y drill hole and provided helpful insights on the stratigraphy in the Westland Development No. 1-1J1E, Westland Development Corporation No. 1-Y, and Atrisco Grant No. 1 drill holes.

Attribute_Accuracy:
Attribute_Accuracy_Report: Data were entered and checked by the geologist that made the field observations. 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 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 (Arc/Info) 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 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 95 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 1:36,000-scale, color, aerial photographs taken on June 13, 1994, and August 5, 1996, and 1:40,000-scale, color infrared, aerial photographs taken on May 5, 1991. Most of the contacts on this map were transferred from the aerial photographs using a Kern PG-2 stereoplotter. The locations of the Westland Development No. 1-1J1E and Atrisco Grant No. 1 drill holes were determined with the aid of aerial photographs using a Kern PG-2 stereoplotter. The location of the Westland Development Corporation No. 1-Y drill hole was determined by David A. Sawyer, of the U.S. Geological Survey, with the aid of a global positioning system (GPS) unit.
