Geologic Mapping
headline image

Geological Mapping provides the underpinning of most research carried out by our organization. Our goal is to provide state-of-the-art geological maps of sufficient detail to be of benefit for practical applications for the state of New Mexico. These maps can address a wide range specific topics, such as location of geological resources, including mineral and petroleum resources and groundwater, geological hazards, which are all relevant to natural resource use, city planning, and education.

Hydrogeology of the EspaƱola Basin & Santa Fe Area
headline image

The southern Española Basin, in the Santa Fe region, was the focus of a multi-year, multi-disciplinary hydrogeologic study by the Aquifer Mapping Program, in collaboration with the New Mexico Office of the State Engineer (NMOSE), the U.S. Geological Survey (USGS) and other agencies. The purpose of this study was to improve the understanding of the water resources within the basin, which serves as the primary source of drinking water for most of the area’s population.

Hydrogeology of the Placitas Area
headline image

The characterization of the Placitas area hydrology in the late-1990s was an important step for water resource planning and development. Local water levels were declining due to increased population and demand on groundwater supplies, with drought conditions in the mid-1990s. The Bureau of Geology initiated a study in 1997 to characterize the availability and quality of groundwater and surface water resources in the Placitas area. Findings were interpreted with detailed geologic maps and cross sections that supported a hydrogeologic conceptual model of groundwater flow and occurrence. The study was completed in 2002 and has been incorporated into the Placitas Area Development Plan by Sandoval County.

Upper Paleozoic Stratigraphy, central NM
headline image
Bruce Allen

A variety of geological studies involving Upper Paleozoic strata, conducted during the mid-twentieth century, produced a preliminary stratigraphic nomenclature for Carboniferous and Permian sedimentary rocks in New Mexico, and a general understanding of the lithostratigraphy, age and distribution of these rock units. Ongoing investigations by geologists from the NMBGMR, universities, museums, and industry are aimed at refining this understanding. For example, strata pertaining to the Pennsylvanian System are often poorly delineated and/or subdivided on geologic maps, due in large part to their lithostratigraphic complexity and a loosely defined stratigraphic nomenclature. Progress has been made during the past 15 years toward improving the stratigraphic nomenclature for Upper Paleozoic strata in New Mexico, and documenting stratigraphic patterns, both of which should provide a better foundation for ongoing and future studies of these rocks.
