Cryogenian in Death Valley

Map showing outcrop of Neoproterozoic Tectonostratigraphic units in Death Valley and the Panamint Mountains. This map was created with the help of students from Harvard Field Camp. The boxed areas show areas mapped during Field Camp in 2012, 2013, and 2015.

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.
