Institut für Geowissenschaften Mathematisch-Naturwissenschaftliche Fakulität Universität Potsdam Tectonic and Climatic Controls on Orogenic Processes: The Northwest Himalaya, India Dissertation zur Erlangung des akademischen Grades Doktor der Naturwissenschaften “doctor rerum naturalium” in der Wissenschaftsdisziplin “Geologie” eingereicht an der Mathematisch-Naturwissenschaftlichen Fakultät der Universität Potsdam von Dipl.-Geol. Rasmus Christoph Thiede Geb. 12.01.1972 in Kiel Potsdam, November 2004 Abstract & Kurzfassung Abstract The role of feedback between erosional unloading and tectonics controlling the development of the Himalaya is a matter of current debate. The distribution of precipitation is thought to control surface erosion, which in turn results in tectonic exhumation as an isostatic compensation process. Alternatively, subsurface structures can have significant influence in the evolution of this actively growing orogen. 40 39Along the southern Himalayan front new Ar/ Ar white mica and apatite fission track (AFT) thermochronologic data provide the opportunity to determine the history of rock-uplift and exhumation paths along an approximately 120-km-wide NE-SW transect spanning the 40 39greater Sutlej region of the northwest Himalaya, India.
