Ediacaran-Cambrian Boundary in Mongolia

The Ediacaran-Cambrian transition in SW Mongolia

The Ediacaran-Cambrian Transition in SW Mongolia


The Zavkhan Terrane in SW Mongolia hosts carbonate-rich, expanded (<2 km), fossiliferous sections of the latest Ediacaran through earliest Cambrian. My work here focuses on better characterizing the rate and tempo of evolutionary change during the earliest Cambrian. I do this by using a combination of small shelly fossil (SSF) biostratigraphy, carbon isotope chemostratigraphy, geologic mapping, and sequence stratigraphy.
