Piedmont alluvium (middle Pleistocene) — Poorly to moderately sorted, moderately lithified pebble and
cobble gravel and pebbly sand. Consist of pebbles to cobbles of limestone and Precambrian metamorphic
and igneous rocks such as granite, quartzite, and metarhyolite. Soil development is variable and multiple
buried soils with stage II to III calcium-carbonate morphology are present. Unit is offset by the Hubbell
Spring fault. Thickness 4 to 5 m (?).
Xbs
Piedmont alluvium (Upper Santa Fe Group, upper Pliocene (?) to lower Pleistocene) — Poorly to
moderately sorted, well-lithified pebble and cobble gravel and pebbly sand. Consists of pebbles to cobbles

COMMENTS TO MAP USERS
A geologic map displays information on the distribution, nature, orientation, and age relationships
of rock and deposits and the occurrence of structural features. Geologic and fault contacts are
irregular surfaces that form boundaries between different types or ages of units. Data depicted
on this geologic quadrangle map may be based on any of the following: reconnaissance field
geologic mapping, compilation of published and unpublished work, and photogeologic interpretation.
Locations of contacts are not surveyed, but are plotted by interpretation of the position of a given
contact onto a topographic base map; therefore, the accuracy of contact locations depends on the
scale of mapping and the interpretation of the geologist(s). Any enlargement of this map could cause
misunderstanding in the detail of mapping and may result in erroneous interpretations. Site-specific
conditions should be verified by detailed surface mapping or subsurface exploration. Topographic
and cultural changes associated with recent development may not be shown.
Cross sections are constructed based upon the interpretations of the author made from geologic
mapping, and available geophysical, and subsurface (drillhole) data. Cross-sections should be used as
an aid to understanding the general geologic framework of the map area, and not be the sole source
of information for use in locating or designing wells, buildings, roads, or other man-made structures.
The map has not been reviewed according to New Mexico Bureau of Geology and Mineral Resources
standards. The contents of the report and map should not be considered final and complete until
reviewed and published by the New Mexico Bureau of Geology and Mineral Resources. The views and
conclusions contained in this document are those of the authors and should not be interpreted as
necessarily representing the official policies, either expressed or implied, of the State of New Mexico, or
the U.S. Government.

Blue Springs Schist — Rusty red to brown quartz-chlorite-garnet schist. Within a few meters of the range
front fault, the rock is a purplish-green chlorite-sericite (?)-quartz schist. Fishhook-shaped and lenticular
lenses and pods of deformed vein quartz, from mm to cm in width, and up to 10s of cm in length, are
abundant and locally may comprise up to 50% of the rock. Contains two well developed foliations. S1 is
a transposition layering defined by quartz lenses, and S2 is the dominant, northeast trending schistosity. A
third cleavage, S3 is variably developed and crenulates S2.

Popatosa Formation (Lower Santa Fe Group, middle to upper Miocene) — Pink to white sandstone,
white sandy conglomerate, and minor red mudstone. Sandstones are moderately lithified, poorly sorted,
medium- to very fine-grained, with subequal amounts of subangular to subrounded quartz grains and lithic
fragments. Lithic fragments are intermediate volcanic rocks and red and black chert. Broad, probably
eolian crossbeds are locally present. Mudstones are thin with carbonate concretions. Conglomerates are
moderately to strongly lithified with rounded to angular pebbles and cobbles of limestone, metasedimentary
rocks, pink to red granite, rhyolite, plagioclase-phyric andesite, and brown quartz sandstone in a matrix
of white coarse sand. Thickness unknown; at least 2600 m in the Socorro basin (Cather, et al., 1994), and
probably hundreds of m in the Grober-Fuqua #1 well to the west (Hudson and Grauch, 2003; B. Brister,
personal communication 2004).

ACKOWLEDGEMENTS
Sierra Ladrones Formation (Upper Santa Fe Group, lower Pleistocene to Pliocene) — Poorly lithified
sandy deposits transitional between axial fluvial and piedmont slope. Northernmost exposures are poorly
lithified yellowish red (5YR 5/6) pebbly sand and silty sand and contain buried calcic soils. Discontinuous
southern exposures around Ojo Jediondilla are light brown to pinkish brown silty sand, and poorly lithified
sparsely crossbedded gray and light pinkish gray pebble conglomerate with coarse sandy matrix. Clasts
are gray, purple, and lavender intermediate volcanic rocks. Nomenclature after Cather (1997). Thickness
unknown; base and top not exposed.

PALEOZOIC ERA
Sequence of piedmont-slope alluvial deposits marking local base level for mountain front drainages.
Piedmont units and surfaces diverge in elevation westward towards the Hubbell Spring fault due to multiple
movements on the fault. Deposits differentiated by topographic position, soil development (see appendix
for descriptions of soil pits) and degree of constructional surface preservation. Deposits are dominated by
sandy gravel with variable sorting and imbrication.

Baca Formation (lower to middle Eocene) — Dark red conglomerate and sandstone. Conglomerate is
composed of 60% clasts to 0.4 m of brick red, crossbedded and ripple-marked fine- to medium-grained
sandstone, 25% gray limestone, and 15% metamorphic and volcanic rocks. Reduction spots are common
on the sandstone clasts. Flattened clasts are strongly imbricated, indicating a paleocurrent direction to the
west. Medium to thick beds of conglomerate beds are interbedded with ~10% sandstone beds. Sandstone
is well lithified, medium- to thick-bedded, and coarse. The complete section is not exposed, but it is up to
425 m thick in the Albuquerque Basin (Lozinsky, 1994).
