Introduction
This report describes the geology of the Albuquerque 30’ x 60’ quadrangle in north-central New Mexico. The compilation summarizes and integrates recent geologic mapping and various topical studies carried out between 1996 and 2002 under the U.S. Geological Survey (USGS) study of the “Middle Rio Grande Basin” by geologists from the USGS, the New Mexico Bureau of Geology and Mineral Resources (NMBGMR), the University of New Mexico, the American Museum, the Arizona Geological Survey, the South Dakota School of Mines and Technology, Washington University, and consulting firms. This study was undertaken to investigate geologic factors that influence ground-water resources of the Middle Rio Grande Basin, and to provide, at a regional scale, new insights into the complex geology of this portion of the Rio Grande rift.
