West-central Argentina: Sierra Valle Fertil

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.
