Abstract:
The Preliminary Geologic Map of the Albuquerque-Rio Rancho Metropolitan Area and Vicinity, Bernalillo and Sandoval Counties, New Mexico is a digital geologic compilation of sixteen 7.5-minute quadrangles, comprising an area of about 2500 km2 of the Albuquerque basin of north-central New Mexico. This compilation, prepared at a scale of 1:50,000, depicts the surface and subsurface geology for the cities of Albuquerque and Rio Rancho and surrounding areas. It was completed in order to better characterize geologic controls on groundwater resources and geologic hazards for this rapidly growing urban region. Geographic Information System (GIS) data and graphics files are available through <http://geoinfo.nmt.edu/publications/openfile/496> and will be followed by a report that describes the geology of the map area. Geologic units exposed in the map area range from Proterozoic granite and schist through modern alluvium. Geologic features in the area reflect Proterozoic collisional events and pluton emplacement, followed by the late Paleozoic Ancestral Rocky Mountains, Late Cretaceous-Paleogene Laramide, and (mostly) Neogene Basin-and-Range tectonic events. The compiled geology emphasizes Cenozoic features, including stratigraphy and structures related to Laramide transpression and subsequent Basin-and-Range extension. The map area crosses parts of the Santo Domingo, Calabacillas, and Belen subbasins; the Calabacillas subbasin occupies most of the map area. Syn-Laramide deposition is recorded by the upper Paleocene and Eocene Diamond Tail and Galisteo Formations, which document fluvial drainage from basement-cored highlands to the north and west. This was followed by the emplacement of locally voluminous volcanic, volcaniclastic sedimentary, and locally eolian rocks of the Eocene-Oligocene unit of Isleta Well #2, which is recognized only in deep drillholes in the map area. The unit of Isleta Well #2 is more than two kilometers thick and is largely confined to down-dropped intrabasinal fault blocks. The unit of Isleta Well #2 is correlative to the Spears Group (south) and Espinaso Formation (east). During late Oligocene time, the area underwent erosion prior to burial by Santa Fe Group sediments, leaving local accumulations of ventifacts of volcanic tuff cobbles along the contact between the Zia Formation and the underlying Galisteo and Menefee formations. The upper Oligocene-lower Pleistocene Santa Fe Group represents the sedimentary and volcanic fill of the Rio Grande rift. Eolian and fluviatile deposits of the Zia Formation were laid down during early Miocene time along the northwestern margin of the Albuquerque basin; fluviolacustrine deposition occurred during late Oligocene time just northeast of the map area. Miocene uplift of the Sandia Mountains is recorded by fluviatile conglomeratic deposits of the Sierra Ladrones Formation, which contain granitic and sedimentary rocks derived from the Sandia Mountains as well as minor amounts of hypabyssal intrusive rocks associated with igneous activity in the nearby Ortiz Mountains. Deposits of the Cerro Conejo and Arroyo Ojito Formations record relatively rapid extension that happened during middle and late Miocene time. The Arroyo Ojito Formation coarsens upward and culminates with conglomeratic sandstone of the Picuda Peak Member. The Arroyo Ojito Formation is locally capped by petrocalcic soils that are well preserved on downthrown fault blocks. Sedimentation resumed by Pliocene time with deposition of the Ceja and Sierra Ladrones Formations. An unconformity is recognized between the upper Miocene Arroyo Ojito Formation and Pliocene Ceja Formation. This Mio-Pliocene unconformity, called the Rincones paleosurface, is exposed along the northwestern basin margin. This paleosurface is delineated locally by petrocalcic soils that exhibit stage III+ and V+ pedogenic carbonate morphology developed on the Navajo Draw Member and Picuda Peak Members of the Arroyo Ojito Formation, respectively. This unconformity represents of lacuna of varying duration, controlled by timing of stratigraphic onlap of fluvial deposits of the Atrisco and Santa Ana Mesa Members of the Ceja Formation. The Ceja Formation typically coarsens upsection into gravels and sands. Subsurface correlations, using a database containing 189 wells, document a basinward thickening of the Ceja Formation. Culmination of Santa Fe Group deposition was diachronous and led to the preservation of local depositional tops, which were likely formed by differential tilting and intrabasinal fault activity. The Llano de Albuquerque represents an abandoned constructional basin-floor surface on the Ceja Formation. The constructional top of the Sierra Ladrones Formation is defined by the Las Huertas, Sunport, and Llano de Manzano surfaces. During late Pliocene time, the ancestral Rio Grande, which deposited the axial-fluvial member of the Sierra Ladrones Formation (unit QTsa), flowed within a couple of kilometers of the rift-flanking Sandia Mountains. This axial river subsequently migrated westward where it began incising into the Santa Fe Group basin fill, creating an ancestral Rio Grande Valley. The entrenched Rio Grande Valley formed during at least 4 or 5 episodes of incision and partial backfilling by the trunk valley and major tributary streams, resulting in the formation of a suite of stepped, valley border terrace landforms along the valley margin. Episodic incision by the ancestral Rio Grande left buttress unconformities that mark the lateral extent of typically coarse-grained inset terrace deposits of the Rio Grande Group. Age constraints on inset terrace deposits indicate that aggradation of fluvial deposits occurred near the end of glacial periods. Mapping and comparisons of surface morphology and soil morphological development allow correlations of tributary stream and ancestral Rio Grande terrace deposits to be made across much of the map area. The oldest definitive inset terrace that defines the edge of the Rio Grande Valley is the Lomatas Negras Formation. The latest episode of valley entrenchment and partial backfilling occurred during latest Pleistocene time, after middle Pleistocene terrace deposits of the Arenal Formation and younger tributary stream deposits were incised by the axial river. Deposits of the inner valley floodplain and channel of the Rio Grande are assigned to the Las Padillas Formation. Progradation of tributary alluvium across the inner valley indicates that present discharge on the Rio Grande is inadequate to transport sediment out of the valley. The presence of progressively inset fluvial deposits along the margins of the modern valley indicates that episodes of prolonged higher discharge were necessary to flush sediment and erode the valley. Smaller nonintegrated drainages formed deposits of the piedmont-slope and are difficult to correlate to incisional events of the ancestral Rio Grande. The northern portion of the map area straddles the Ziana anticlinal accommodation zone, which divides the Santo Domingo and Calabacillas sub-basins. To the south, the Calabacillas sub-basin resembles a complexly faulted, east-tilted half graben with a structural bench along the western margin called the Laguna bench. East of the San Ysidro and Zia fault zones, the basin deepens where more than 2 km of the unit of Isleta #2 and nearly 5 km of Santa Fe Group deposits are preserved. Sparse drillhole data suggests that the lower parts of the Santa Fe Group contain mudstones that may be correlative to the Popotosa Formation. Many of the structural features associated with Rio Grande rift extension have antecedents in previous tectonic events. Regional thickness trends support the presence of pre-Neogene tectonic events, such as a late Paleozoic structural culmination near the crest of Ziana anticlinal accommodation zone. A thinner succession of Mesozoic strata on the hangingwall of the San Ysidro fault suggest more than 400 m of reverse movement (possibly with an unresolved component of strike-slip separation) occurred during the Laramide orogeny. This was followed by nearly 2 km of pre-Miocene normal fault movement. The San Ysidro fault presently marks the boundary between thick deposits of the unit of Isleta Well #2, indicating that considerable pre-Miocene extension had occurred prior to deposition of the Zia Formation. The eastern structural margin of the Albuquerque basin is marked by the rift-flanking Sandia Mountains. The East Heights area of Albuquerque is underlain by a series of intrabasinal normal faults that broadly define the eastern structural margin of the basin. Pleistocene deposits, such as the Edith Formation, are displaced by normal faults, indicating continued tectonic activity in the region. The structural configuration of the map area indicates that much of the City of Albuquerque derives groundwater from the Ceja and Sierra Ladrones Formations. The City of Rio Rancho generally derives much of its water from older, deeper and more consolidated aquifers of the Arroyo Ojito and Cerro Conejo formations.
Purpose:
Geologic map compilation at a scale of 1:50,000 of sixteen 7.5-minute quadrangles of the Albuquerque and Rio Rancho metropolitan area and vicinity, Bernalillo and Sandoval Counties, New Mexico. This compilation summarizes the results of geologic mapping and stratigraphic studies completed 1994-2004 by the New Mexico Bureau of Geology and Mineral Resources, U.S. Geological Survey, University of New Mexico, New Mexico Institute of Mining and Technology, to improve understanding of the geology of the region. Includes geologic compilation and generalization of the geology for the Alameda, Albuquerque East, Albuquerque West, Arroyo de las Calabacillas, Bernalillo, Bernalillo NW, Cerro Conejo, La Mesita Negra SE, Loma Machette, Placitas, Sandia Crest, San Felipe Pueblo, Tijeras, and The Volcanoes 7.5-minute quadrangles (1:24,000 original scale). The Los Griegos 7.5-minute quadrangle was mapped at a reconnaissance level of 1:50,000. Geologic map compilation is released in preliminary form at New Mexico Bureau of Geology and Mineral Resources Open-file Report 496. This draft geologic map is preliminary and will undergo revision. After this map has undergone scientific peer review, editing, and final cartographic layout and production, it will be released in NMBMGR Geologic Map (GM) series. The final version will receive a new GM number and will supercede this preliminary open-file report.
Supplemental_Information:
Compilation is based on new 1:24,000-scale geologic mapping for most of the area, completed 1994-2004. Contributing agencies (and associated quadrangles) include:

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).

Attribute_Accuracy_Report:
Attributes were checked by manually comparing plots of the digital data with the source materials. 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. Attributes were queried to establish validity. Smaller features were selectively deleted to reduce clutter at compilation scale; however, many smaller features of the originating coverages were retained because of interpretative ambiguities or database manipulation problems. Completeness_Report: Geologic data were collected and digitized at original resolution (1:24,000 and 1:50,000) and compiled digitally. Component maps required re-projection to Universal Transverse Mercator Zone13N, North American Datum of 1983. Component databases required manipulation to merge on common descriptors for portrayal on a base at 1:50,000 scale. Many features of the component maps were generalized or eliminated. No report is available on details of map generalization.

Process_Description:
Compiled from available GIS data for sixteen 7.5-minute quadrangles at a scale of 1:24.000. The Los Griegos quadrangle was compiled during a reconnaissance by S.D. Connell at a nominal scale of 1:50,000. Initial compilation into coverages using various vintages of ARC/INFO from version 8.2 and older. These were mosaicked into larger coverages using ARC/INFO v. 8.2, then imported into geodatabases using ARC Map 9.2 to complete map layout. Process was completed in 2005. Original data projections in polyconic NAD 27 and UTM NAD 27 and re-projected using Arcinfo v.8.2 to UTM NAD 83. Additional field mapping and aerial photography interpretation and field-checking required substantial changes to be made on the La Mesita Negra SE, The Volcanoes, Arroyo de las Calabacillas, and Loma Machette quadrangles. Minor to moderate changes were made on other quadrangles.
