Summary

Abstract: 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.

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.
