Current Research

My current interest is the Cenozoic E-W extension on the Tibetan Plateau. Ongoing northward drifting of India led to E-directed extrusion of the Tibetan plateau along major strike-slip faults and associated N-S striking rift valleys. These valleys show an incredible change in relief from high summits with spectacular triangle facets in the footwall to rather smooth and less high hills in the hanging-wall parts. Preliminary studies have shown that this contrasting morphological feature becomes apparent in different ages of footwall and hanging-wall rocks. Studies on the brittle tectonics and (U-Th)/He thermochronology in the Xainza Rift valley can improve the knowledge about the kinematics and timing of rifting plus the interactions with the adjacent strike-slip systems. Additionally, dating of rocks with U/Pb, Rb/Sr and Sm/Nd techniques will add substantial information to the network of international studies in Tibet.



Past Research

Graduate Research Assistant

Starting in fall 2000 my Master’s thesis I was working in the Indian part of the Sutlej Valley (Himachal Pradesh, NW-Himalaya) focusing on brittle tectonics to study the kinematics of the late-stage extrusion of a wedge shaped metamorphic unit (Lesser Himalayan Crystalline Sequence, LHCS). Additional dating of pegmatites with Grt Sm/Nd and Mica Rb/Sr techniques shed light on the timing of the tectonic processes.
