Former M.S. student Andy Tholt (now at UC Berkeley) has published his thesis research in Geosphere. In this work, Andy combined field mapping with metamorphic petrology and garnet and monazite geochronology to constrain the boundaries between different tectonic domains in the Famatina margin of Argentina. The results revise existing correlations between metamorphic domains and require that strike-slip deformation played an important role in the tectonic history of this region.
