Abstract:
The Albuquerque 30' x 60' quadrangle spans the Rio Grande rift between the
Colorado Plateau and Great Plains geologic provinces, and includes parts
of the Basin and Range and Southern Rocky Mountains physiographic
provinces. Geologic units exposed in the quadrangle range in age from
Early Proterozoic schist and granite to modern river alluvium. The
principal geologic features of the area, however, chiefly reflect
contractional folding and thrusting of the Late Cretaceous Laramide
orogeny and the Neogene extension of the Rio Grande rift. Significant
parts of the history of the rift in this region are displayed and
documented by the geology exposed in the Albuquerque quadrangle.
Post-Laramide erosion, beginning at about 60 Ma, is recorded by the
Diamond Tail Formation and Galisteo Formation (Upper Paleocene and
Eocene), which are preserved in the Hagan Basin and around the uplifted
margins of the younger Rio Grande rift. Intermediate volcaniclastic
deposits of the Espinaso Formation (upper Eocene and Oligocene) were
shed in and around the contemporaneous volcanic-intrusive complexes of
the Ortiz porphyry belt in the northeastern part of the quadrangle. The
earliest fluvial sediments attributed to extension in the Rio Grande
rift in this area are the Tanos and Blackshare Formations (upper
Oligocene and Miocene) in the Hagan Basin that indicate extension was
underway by 25 Ma. Farther west, the oldest rift-filling sediments are
eolian sand and interdune silty deposits of the Zia Formation (middle to
lower Miocene). Major extension occurred during the Miocene but
subsidence and sedimentation was highly irregular from place to place.
Parts of three rift sub-basins are known within the Albuquerque
quadrangle, each basin locally as deep as about 14,000 ft, separated by
less-extended zones (structural horsts) where the rift fill is much
thinner. The geometry of these early, deep rift sub-basins suggests the
primary extension direction was oriented northeast-southwest.
Significant local folding and uplift within and marginal to the complex
rift seems to have occurred in the late Miocene, accompanied by erosion
and recycling of earlier rift-fill sediments. This deformation may
reflect clockwise re-orientation of the primary extension direction to
its Pliocene and current east-west alignment.
Late Miocene and early Pliocene uplift and erosion were widespread in the
region, as indicated by channeled and local angular unconformities at
the bases of all Pliocene units, especially prominent along basin
margins. These Pliocene fluvial and alluvial deposits (Ceja, Ancha, and
Cochiti Formations and Tuerto Gravel) are all conspicuously coarser
grained than the Miocene beds they cover, particularly near source areas
along the margins of the rift. These observations together indicate the
regional streams flowed at much greater discharge than the Miocene
streams and that the Pliocene onset of cooler, wetter climate worldwide
was the most likely cause. Despite these higher discharge conditions,
it appears that no Pliocene trunk stream flowed through the rift valley
because the youngest Pliocene beds in the basin center are largely fine-
grained, pebbly sand and silt. No Pliocene cobble gravel deposits, or
thick crossbed sets indicative of major stream discharge, have been
documented in the basin center.
Considerable evidence indicates significant regional erosion began in late
Pliocene time, coincident with and following eruption of abundant basalt
from several local centers at about 2.7-2.6 Ma. The onset of central
valley erosion marks the initiation of the first through-flowing, high-
energy trunk stream (the “ancestral” Rio Grande), which most likely was
caused by integration of drainage southward through the Socorro region.
No upper Pliocene fluvial deposits have been identified in the valley
center; rather, a significant unconformity separates beds with medial
(or earliest late) Blancan fauna (older than about 2.2 Ma) from
overlying beds that contain Pleistocene (Irvingtonian; younger than 1.8
Ma) fauna. The oldest Pleistocene fluvial deposits contain tephra beds
from the 1.6 Ma eruption of the Bandelier Tuff as well as abundant
Bandelier pumice. These deposits record the first prolonged episode of
fluvial aggradation within the eroded late Pliocene-early Pleistocene
Rio Grande valley and they reflect the glacial climate-cycle evolution
of a major river system capable of carrying coarse cobble-boulder loads
and creating crossbed sets that were several feet thick. This
aggradation apparently waxed and waned until about 1.2 Ma because the
uppermost fluvial terrace-fill deposits contain tephra from the 1.2 Ma
Bandelier Tuff eruption. This oldest terrace surface is preserved at
Albuquerque International Airport at about 360 ft above the modern
floodplain. Subsequent glacial climate-cycle variations in fluvial
discharge led to episodes of progressive downcutting and terrace
aggradation that are recorded throughout the valley by three other major
terraces at about 300 ft, 150 ft, and 60 ft above the modern floodplain.
The Albuquerque quadrangle covers the largest metropolitan area of New
Mexico and is home to more than 500,000 people in Albuquerque, Rio
Rancho, and Bernalillo.
Purpose:
This compilation summarizes results of detailed geologic mapping completed
from 1996 to 2002 by the U.S. Geological Survey, State agencies, and
universities, and related topical studies to improve understanding of
the geologic framework of ground-water resources in the region.
Supplemental_Information:
Compilation is based on new 1:24,000-scale geologic mapping for most of
the area, completed 1996-2002. Four quadrangles on the western margin
of the sheet were mapped in reconnaissance with the aid of enhanced
satellite imagery by D.A. Sawyer (USGS), based on an unpublished USGS
compilation of geology in the San Juan basin. Two quadrangles in the
southeastern corner of the sheet were mapped in reconnaissance by author
P.L. Williams based on aerial photographs and limited field examination.
No further USGS mapping is underway or planned in this area as of 2004.
Any use of trade, product, or firm names is for descriptive purposes only
and does not imply endorsement by the U.S. Government.
Although this Federal Geographic Data Committee-compliant metadata file is
intended to document the data set in nonproprietary form, as well as in

Attribute_Accuracy:
Attribute_Accuracy_Report: Attributes were checked by manually comparing
hardcopy plots of the digital data with the source materials. Authors and
USGS map editors performed separate reviews.
Logical_Consistency_Report: Map elements were visually checked by the authors
for overshoots, undershoots, duplicate features, and other errors. ARC/INFO
software was used to create topological relations among features. Features
were not duplicated, but coincident lines exist between data layers where
appropriate.
Completeness_Report: Geologic map units were collected and digitized at
appropriate resolution for portrayal on a base at 1:100,000 scale. Data are
complete: no features were eliminated or generalized.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: Geologic contacts, faults, and
other map features were compiled by the first author by hand on
1:100,000-scale topographic base map, generalized from 1:24,000-scale
geologic maps that had been photo-reduced. Horizontal accuracy at map
scale is probably on the order of 130 ft.
