Overview

There are various projects here.

1) Mantle under the San Francisco Craton (South America)

A suite of peridotite xenoliths from diamondiferous kimberlites from this craton provides a first opportunity to characterize the ancient history of this mantle. Fundamental global questions remain about how old is the mantle under South America and whether portions of it have been stable since the Archean. What is its evolution? How does it relate to the formerly joined Congo Craton?

The project would have no fieldwork (sorry…) but would involve mineral and isotope characterization of the rare specimens of mantle material that are available.
