Upper Paleozoic Stratigraphy, central NM
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.

Geology of the Engle and Palomas Basins, Sierra County, New Mexico

Geologists and hydrologists have been interested in basin-fill sediments of the Engle and Palomas Basins in Sierra County since the early 1900s. These Rio Grande rift basins contain packages of sediment shed from the surrounding uplifts over the last ~27,000,000 years. Well logs indicate that these basin-fill deposits, named the Santa Fe Group, are as much as 2 kilometers thick in places.
