  Description:

    Abstract:
      The Albuquerque 1:100,000-scale 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) that 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 (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 feet (4.3 km), 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 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 cross-bed 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 meter-thick cross-bed sets.   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 110 m 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 100 m, 45 m, and 20 m 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 1996-2002 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 (see
      Compilation Methods).  Two quadrangles in the southeastern
      corner of the sheet were mapped in reconnaissance by author
      P. Williams based on aerial photographs and limited field
      examination.  No further USGS mapping is underway or
      planned in this area as of 2004.

  Attribute_Accuracy:
    Attribute_Accuracy_Report: Attributes were checked by manually comparing hard copy 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 40 m.
