James Fassett

I am retired from the USGS following 40 years of research on environments of deposition of energy minerals in the San Juan Basin of NM and CO plus detailed studies of the geochronology of the rocks adjacent to the K-Pg boundary in the SJB. My research on these topics continues into the present. I was the first to fully document Paleocene dinosaurs in the SJB (and the world). i lead the USGS team, in association with the Pakistan G.S.,in the discovery of the giant Thar Desert coal field and was the lead author in the geologic description and quantification of this fileld's coal resources of 78 million metric tons.
