The Sierra Valle Fertil is a crustal cross-section of a volcanic arc formed above a subduction zone about 475 million years ago. It is an extraordinary natural laboratory of a juvenile arc that exposes the 'mafic mothership' that drives petrologic diversity in the deep arc environment. This project was from 2008-2015.
The Kos Pleateau Tuff was chosen as a natural laboratory to study the effects of pyroclastic transport over water. It involved fieldwork on four Greek Islands and Turkey. The team included Joe Dufek (his PhD project), Olivier Bachmann, Sharon Allen and Alain Burgisser.
