Research — Geochronology



(Note: combining a subject and location may provide few or no results.)
Dating the Sands of Time

A new dating method, being developed at the NMBG&MR, uses our state-of-the-art geochronology laboratory, funded by NSF and NM Tech, to determine the age of detrital sanidine (tiny volcanic minerals) from sediments.

New Mexico's Volcanic Hazards

New Mexico is home to many hundreds of volcanoes that erupted during the last several million years. However, the exact timing of these eruptions has proven difficult to determine by many previous studies. An ongoing NSF-funded project, led by NM Bureau of Geology researcher Matthew Zimmerer, examines the timing of eruptions during the last 500,000 years in order to understand the patterns of volcanism in space and time. This information provides the foundation for an assessment of volcanic hazards in New Mexico.
