Cryogenian in Death Valley
The Pahrump Group in Death Valley, CA
The Pahrump Group preserve eukaryotic microfossil assemblages, diverse microbialites, and large negative carbon isotope excursions just below Sturtian-aged glacial deposits. With new geologic mapping, carbon isotope chemostratigraphy, sedimentology, and detrital zircon geochronology, we have constructed a new facies model and refined the tectonostratigraphic history of the Pahrump Group.
An on-going, long-term project is to create a Noeproterozoic tectonostratigraphic and unconformity map. See the map to the right for our work in progress.
