Geophysical observations of the Black Crater intrusion, Brewster County, Texas

The Black Crater intrusion, in Brewster County, west Texas, has a positive magnetic and potassium enrichment radiometric signature, as observed in the recent Texas Alkaline Igneous Belt (TX-AIB) Earth Mapping Resources Initiative (MRI) airborne geophysical survey. A follow-up ground data collection campaign to the intrusion verified the airborne geophysical anomalies and led to the discovery of mineralization in a previously unrecognized magmatichydrothermal system. Geochemical analyses are being conducted to determine if critical minerals are present.
