Title:
Geologic map of the Tetilla Peak quadrangle, Santa Fe and Sandoval Counties, New Mexico
Abstract:
This digital geologic map summarizes all available geologic information for the Tetilla Peak quadrangle located immediately southwest of Santa Fe, New Mexico. The geologic map consists of new polygon (geologic map units) and line (contact, fault, fold axis, dike, flow contact, hachure) data, as well as point data (locations for structural measurements, geochemical and geochronologic data, geophysical soundings, and water wells). The map database has been generated at 1:24,000 scale, and provides significant new geologic information for an area of the southern Cerros del Rio volcanic field, which sits astride the boundary of the Espanola and Santo Domingo basins of the Rio Grande rift.
The quadrangle includes the west part of the village of La Cienega along its eastern border and includes the southeasternmost part of the Cochiti Pueblo reservation along its northwest side. The central part of the quadrangle consists of Santa Fe National Forest and Bureau of Land Management lands, and parts of several Spanish-era land grants.
Interstate 25 cuts through the southern half of the quadrangle between Santa Fe and Santo Domingo Pueblo. Canada de Santa Fe, a major river tributary to the Rio Grande, cuts through the quadrangle, but there is no dirt or paved road along the canyon bottom.
A small abandoned uranium mine (the La Bajada mine) is found in the bottom of the Canada de Santa Fe about 3 km east of the La Bajada fault zone; it has been partially reclaimed.
The surface geology of the Tetilla Peak quadrangle consists predominantly of a thin (1-2 m generally, locally as thick as 10? m) layer of windblown surficial deposits that has been reworked colluvially. Locally, landslide, fluvial, and pediment deposits are also important. These colluvial deposits mantle the principal bedrocks units, which are (from most to least common): (1) basalts, basanites, andesite, and trachyte of the Pliocene (2.7-2.2 Ma) Cerros del Rio volcanic field; (2) unconsolidated deposits of the Santa Fe Group, mainly along the western border, in the hanging wall of the La Bajada fault zone, but locally extending 2-3 km east under the Cerros del Rio volcanic field; (3) older Tertiary volcanic and sedimentary rocks (Abiquiu?, Espinaso, and Galisteo Formations); (4) intrusive rocks of the Cerrillos intrusive center that are roughly coeval with the Espinaso volcanic rocks; and (5) Mesozoic sedimentary rocks ranging in age from the Upper Triassic Chinle Formation to the Upper Cretaceous Mancos Shale.

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
    • David A. Sawyer
    • Ralph R. Shroba
    • Scott A. Minor
    • Ren A. Thompson
    • Jeffrey C. Blossom
    • Thomas R. Fisher
    • Ronald R. Wahl
    • D. Paco Van Sistine
  2. Who also contributed to the data set?
    Production of this map was funded by the National Cooperative Geologic Mapping Program. Thanks are given to John S. Pallister, Program Coordinator. Permission from the Governor's and council of Pueblo de Cochiti is gratefully acknowledged. Jacob Pecos, Gary Valdo, Dave Gordon, Michael Quintana, and Lee Suina of the Cochiti Environmental Protection Office (CEPO) rendered critical input and graciously provided cooperative assistance; Donald Suina of the Cochiti Game and Fish Department oversaw the safety and security of work conducted on Pueblo de Cochiti lands. Don Diego Gonzales facilitated interaction with the Pueblo de Cochiti and supported interactions with the Pueblo and essential cooperative training. Without the pioneering work of John W. Hawley and J. Michael Kernoodle, or the cooperation and leadership of Charles E. Chapin of the New Mexico Bureau of Mines and Mineral Resources, we would not even have conceived of the work focused on hydrogeologic problems in the "Middle Rio Grande."
    Collegial interactions with Gary A. Smith of the University of New Mexico and David P. Dethier of Williams College have kept us honest and furthered our collective work; complete reviews by Dethier, Paul S. Williams, Tom Judkins, and Alex Donatich and partial reviews by William A. Cobban, Steve Condon, and Jim Cole corrected many errors. T.R. Brandt, N. Shock, T.R. Fisher, and R. Schumann assisted in developing the digital database and the related metadata. Any errors or problems remaining are solely the responsibility of the authors.

Why was the data set created?

The purpose of this mapping was to determine the bedrock geology that would control or impact ground-water flow from the Espanola basin into the Santo Domingo basin. As it is a multi-purpose geologic map, it is suitable as the geologic layer for any variety of interdisciplinary investigations incorporating geology as a theme.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Original data were drawn on a mylar greenline and checked by David Sawyer for bedrock units and Ralph Shroba for surficial units. 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. Map compilation was subjected to technical review by co-authors and several reviewers through the formal USGS review process. This map has been thoroughly reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature.
  2. How accurate are the geographic locations?
    Lines were primarily mapped by photo-interpretation of 1:24,000-scale color aerial photographs using a PG-2 photogrammetric plotter that rectified the position and transferred it to a base map. Estimated horizontal accuracy is better than or equal to 10 meters. This accuracy is consistent with reference to the 1:24,000-scale base map and its approximate horizontal accuracy of 40 feet (12 meters). Elevation data that are included in the database are from digital line graph data from 1:24,000-scale 7.5' quadrangles.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Data are complete: no features that could be accurately represented at the compilation scale of 1:24,000 were eliminated or generalized. Unit properties are described in the text explanation. A small portion of the map on lands of Santo Domingo Pueblo was not visited or field checked. The smallest area represented is approximately 110 square meters. All geospatial database elements are attributed.
  5. How consistent are the relationships among the observations, including topology?
    Map elements were visually checked for overshoots, undershoots, duplicate features, polygon closure, and other errors by the author and by the GIS technician(s) that 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 at least two other geologists for consistency with basic geologic principles and general conformity to USGS mapping standards.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
Access_Constraints: None
Use_Constraints:
None. However, acknowledgment of the U.S. Geological Survey as source of the data would be appreciated in products derived from these data. These data are not intended to be used at scales larager than 1:24,000.

  2. What's the catalog number I need to order this data set?
  3. What legal disclaimers am I supposed to read?
    Although these digital spatial data have been subjected to rigorous review and are substantially complete, it is released on the condition that neither the USGS nor the United States Government may be held liable for any damages resulting from their authorized or unauthorized use.
  4. How can I download or order the data?
