Deciphering the Dariv

Claire Bucholz, a Ph.D. candidate in the MIT-WHOI Joint Program, studies rocks in an ancient subduction zone now lying in the heart of land-locked Mongolia. In particular, she has spent the last two summers, building an understanding of a unique island arc-related alkaline fractionation sequence in the remote Dariv Mountain Range. As part of a broader interest in chemical mass transfer between various reservoirs in the earth, a current focus is the chemical recycling processes that occur in subduction zones and the origin and evolution of the continental crust. Combining fieldwork, petrology, major & trace element geochemistry, geochronology, experimental petrology, and modeling, Claire's research exemplifies the extremely multi-disciplinary nature of research in this area as well as the unique fieldwork opportunities it provides. In Summer 2012 Claire was accompanied by undergraduate Ben Thompson as part of a UROP project. To enquire about similar UROP opportunities years in the 2013 field season, email Oliver Jagoutz ([email protected]). Video by Helen Hill (http://http://eaps-www.mit.edu/people/hlh)
