Mimbres Basin Water–table Levels Through Space and Time Mimbres Basin, NM
June 29, 2021

A new method for developing maps of water-tables employed in the Mimbres Basin in southern New Mexico indicates how groundwater pumping and recharge have changed water-table levels through time. Notably, the region from Deming south to Columbus experienced water-level declines of up to 75 feet since 1980, likely a result of pumping for agricultural use.

Zuni Mountains Tell a Story of Complex Uplift Zuni Mountains, NM
June 28, 2021

Rocks in the Zuni Mountains record two distinct intervals of uplift over the last 80 million years preserved as cooling signatures in apatite mineral grains, according to a new paper published in Tectonics by New Mexico Bureau of Geology Field Geologist Dr. Jacob Thacker and Senior Geophysicist/Field Geologist Dr. Shari Kelley. The initial phase occurred during the Laramide orogeny, a deformation event that affected a wide swath of the western U.S. from 90 to 40 million years ago. The second uplift phase occurred at or after 20 million years ago, maybe as recently as 10 million years ago, and may be the result of convection in the mantle.

Rocks in Northwestern NM Record Rapid Growth of San Juan Mountains San Juan Basin, NM
June 11, 2021

About 65 million years ago, a river system rapidly depositing sediments eroded off of the San Juan Mountains in Colorado formed the Ojo Alamo Sandstone located in the modern-day San Juan Basin, says a new paper published in Geosphere by New Mexico Bureau of Geology Field Geologist Dr. Kevin Hobbs. The article details how this little-studied unit likely formed as an amalgamation of multiple rivers all depositing predominantly sand carried south from the uplands to the north.

"Helium in New Mexico" Podcast with Ron Broadhead
May 11, 2021

Ron Broadhead, emeritus principal petroleum geologist at New Mexico Bureau of Geology and Mineral Resources, was interviewed for the "Stone Notes" podcast about helium in New Mexico. The discussion focuses on helium exploration with some references to the research paper by Ronald Broadhead titled "Helium in New Mexico – geologic distribution, resource demand, and exploration possibilities”. Some highlights include discussing which reservoirs are ideal for helium production. Tune in to learn more about this interesting New Mexico resource.
