The New Mexico Bureau of Geology and Mineral Resources has published geoscience research and information since its inception in 1927. Our publishing program serves both the professional geologic community and the general public. Many of our publications are now offered in electronic format, and most of those are available for free download. However, many of our older publications and selected newer publications are available in print.
We also carry publications from the New Mexico Geological Society (NMGS), United States Geological Survey (USGS), as well as other publishers.
Below is a selection of the more recent publications we have available:
Open-file Report-611 — Geology of the Eastern Plains of San Agustin and Upper Alamosa Creek
By: Daniel J. Koning and Alex Rinehart, 2021
This report gives a detailed treatment of the geology of the eastern Plains of San Agustin and the upper (northern) reaches of Alamosa Creek (aka Alamosa basin). We synthesize previous studies of geology and provide new detail on basin fill stratigraphy and sedimentology. This report is a complement to a hydrogeologic study (due to be released 2021; summarized in OFR-615) regarding groundwater movement, age, and storage under the Plains of San Agustin and the upper Alamosa Creek watershed.
The Plains of San Agustin is a 55 mi long, 10–20 mile wide geographic feature located about 120–150 miles southwest of Albuquerque. It is comprised of a series of hydraulically closed basins that collectively form a northeast-southwest topographic depression. A set of low hills south of Datil divide the topographic depression into the West and East San Agustin basins. This report focuses on the East San Agustin basin, which hosts the Very Large Array (VLA) radio telescope observatory. It is also where the Augustin Plains Ranch, LLC, has proposed a contentious, large-scale groundwater extraction and artificial recharge project. Three grabens have been identified in the East San Agustin basin, where the Earth’s crust has subsided along fault lines and the sedimentary basin fill is relatively thick. The Augustin Plains Ranch project is located in the north-south trending North graben, which has a bedrock floor and overlying strata that are tilted westwards towards faults at the base of the eastern Datil Mountains. Basin fill thickens westwards towards these faults, where it is at least 3,500 ft thick.
The upper reaches of Alamosa Creek flows 15 miles south in a ~9 mi wide, north-south trending topographic low that we call the upper Alamosa basin. This basin coincides with the northern Winston graben. This geologic structure is tilted westwards towards faults at the eastern foot of the Black Range. Basin fill thus thickens westward, as it does for the North graben, and is estimated to be as thick as 4,600 ft.
The geology of the study area has four main components: older sedimentary bedrock, volcanic bedrock, basin fill, and valley-fill alluvium The bedrock consists of volcanic and volcaniclastic rocks of the Mogollon-Datil volcanic field that overlie 750–1,900 ft of sandstones and mudstones of the Eocene-age Baca Formation. The lower Spears Group, composed mainly of tuffaceous debris flows and mud flows, comprises the lower 1,500–2,000 ft of the Mogollon-Datil field volcanic package and is interpreted to be an aquitard. Above the lower Spears Group lies 1,300–5,900 ft-thick sequence of interbedded ash-flow tuffs (ignimbrites), lava flows, volcaniclastic sediment (assigned to the middle-upper Spears Group) and minor tongues of non-volcanic, windblown sand (eolianites). The volcaniclastic sediments of the middle to upper Spears Group probably are poor aquifers. Eolianites are inferred to have both intergranular and fracture flow, and likely have higher permeability than the volcaniclastic sediments.
In addition, fracture networks may be sufficiently open and connected in the lava flows and tuffs, particularly the regionally extensive and thick ignimbrites, to allow appreciable groundwater movement.
Basin fill strata of the Santa Fe Group can be subdivided into the following facies: proximal to medial piedmont, distal piedmont, basin floor (or alluvial flat), and playa. In the southern part of the North graben, we recognize piedmont versus basin floor facies using geophysical-well-log and cuttings criteria from three wells with detailed wireline logs and/or cuttings records. Here, we interpret a western piedmont facies interfingering eastward with a finer-grained basin floor facies, which in turn interfingers eastward with an eastern piedmont facies. Two to three, “layer-cake” stratigraphic intervals can be locally recognized using inferred disconformities in wireline data or abrupt lithologic changes, but mapping their lateral extent away from wells awaits further study.
Overall, the texture of the basin fill in the southern North graben, the location of the proposed well field by Augustin Plains Ranch, is sand and clayey-silty sand that is capped by a 300–350 ft-thick, upper gravel-bearing interval with a notably high proportion of clay. This upper gravel-bearing interval experienced a dramatic eastward progradation in the Pleistocene that could be related to a slow down of faulting or paleoclimatic changes. Analyses of sonic and density-porosity well-log data from the 3,500 ft-deep SA-221 well indicates a general range in sand porosity of 5–25%, decreasing with depth. The notable clay content of subsurface sediment here—and also inferred for the northern part of the North graben and most of the C-N embayment—makes these areas susceptible to groundwater-related subsidence if there is large-scale pumping. In addition, the high clay content in the coarse, uppermost western piedmont unit of the southern North graben may impede infiltration from the surface to the water table. In the North graben, piedmont deposits of the lower part of the upper Santa Fe Group appear to have the highest proportion of high-porosity sands.

The Geology of Southern NM Parks, Monuments, and Public Lands
By: Peter A. Scholle, Dana S. Ulmer-Scholle, Steven M. Cather, Shari A. Kelley, and [eds.], 2020
Southern New Mexico has a wonderful combination of spectacular scenery and a sparse population. The state’s diverse and interesting geology is reflected in its numerous National and State parks and monuments (including Carlsbad Caverns and White Sands) as well as other publicly accessible lands, which range in size from the multi-million acre Gila wilderness to small roadside turnoffs and picnic areas. This book, crafted by geoscientists but written for the interested public, provides an understanding of the exposed rock units that record more than 1.7 billion years of geologic and biologic changes in this region. With nearly 400 full-color photographs, geologic maps, and illustrations, this book illuminates not just the rocks and fossils of southern New Mexico, but also archaeological/historical sites as well as the water, mineral, and energy resources of the region.

Open-file Report-607 — Sunshine Valley Hydrogeology Study
By: Geoffrey Rawling and Shari Kelley, 2020
The regional hydrologic importance of the Sunshine Valley of northern Taos County, New Mexico, is belied by its remote location and sparse population. This is due to the large increase in flow of the Rio Grande in the reach adjacent to Sunshine Valley, and the transfer of 1,752 acre-feet per year of water rights downstream from the valley as part of the Aamodt Settlement Agreement. There has been no detailed hydrologic investigation of the region since the 1950s. This study integrates new physical and chemical hydrologic data, field geophysical investigations, and previous work and historical data to elucidate the hydrologic regime in the valley and document changes to the groundwater system since the 1950s. A hydrologic conceptual model and water budget for the aquifer system were prepared.

Special Publication-14 — The Geology of the Mount Taylor Area
By: Bonnie A Frey, Shari E. Kelley, Kate E. Zeigler, Virginia T. McLemore, Fraser Goff, and Dana S. Ulmer-Scholle, 2020
The Mount Taylor area occupies a crossroad where geologic history, human history, and societal impacts intersect. Situated on the eastern edge of the Colorado Plateau and flanking the transition zone to the Rio Grande rift, Mount Taylor is a late Pliocene stratovolcano located on the Jemez Lineament, an enigmatic NE-trending alignment of late Cenozoic volcanic centers. Mount Taylor lies along the southeast margin of the San Juan Basin bounded by the Zuni (south) and Nacimiento (east) uplifts. Mount Taylor also has some of the richest uranium deposits in the United States.
The human history of the Mount Taylor region is no less compelling. Indigenous communities lived here for thousands of years despite Spanish conquest and the establishment of land grants. In the 1800s, settlement of this U.S. territory came, as did the railroad and timber industries, and later the uranium boom and its lasting legacy. Corridors of commerce opened with Route 66, succeeded by Interstate 40. The designation of Mount Taylor as a Traditional Cultural Property recognizes the mountain's importance to Native, Spanish and U.S. cultures.
The papers in this online volume, NMGS Special Publication 14, were written for the 2020 NMGS fall field conference guidebook. The field conference was postponed to 2021, due to the Covid-19 pandemic. The papers in this volume cover a spectrum of topics, ranging from geologic studies and mining history to the effects of mining on the population and the environment today.

Geologic Map-80 — Geologic Map of Mount Taylor Volcano Area, New Mexico
By: Fraser Goff, Shari A. Kelley, Cathy J. Goff, David J. McCraw, G. Robert Osburn, John R. Lawrence, Paul G. Drakos, and Steven J. Skotnicki, 2019
The Geologic Map of the Mount Taylor Volcano Area, New Mexico is a 1:36,000 compilation of six recent NMBGMR 1:24,000 geologic quadrangles that encompass this extinct composite stratovolcano. Mount Taylor is New Mexico’s second-largest volcano after the Valles Caldera in the Jemez Mountains. This timely map and accompanying report, resulting from over a decade of thorough work, synthesizes the current geologic understanding of such an important landscape feature of the state.
For such a complex volcanic landform, the report provides an exhaustive description of the volcano area in an easy-to-read format. In addition to providing a detailed description of each of the map’s 339 units and dikes, it documents the volcano’s history and history of research, its geochemical and petrographic composition, the phases of its construction ranging from the initial to the terminal eruptions, 3.72–1.26 million years ago, and its subsequent erosion, resulting in the summit Amphitheater and its extensive apron of debris. It describes the surrounding volcanic centers, the structure of the area, and the extensive dikes and maars. After touching on the water resources, hydrothermal alteration and mineralization, and geothermal potential, the report concludes with a conceptual model of volcano evolution.
Available folded or rolled on field-durable media. There is also a puzzle version of this geologic map.

Guidebook-70 — Geology of the Raton-Clayton Area
By: Frank Ramos, Matthew J. Zimmerer, Kate Zeigler, and Dana Ulmer-Scholle, 2019
The Raton-Clayton area is known for its intertwined geologic, biologic, and human histories. Over thirty years have passed since the NMGS Fall Field Conference was last held in northeastern NM. Recently, numerous workers have focused on Mesozoic stratigraphy, Laramide tectonics, late Quaternary volcanism, landscape evolution, groundwater characterization, and induced seismicity. The field conference will highlight aspects of the current and ongoing research. The area hosts spectacular and diverse geology, often overlooked by travellers to this part of the state. We will examine the geologic, biological, and human histories of the mesas, volcanic peaks, and numerous valleys that riddle the landscape of the hi-lo country.
