The focus of my PhD is to better understand the climatic change from mid-miocene until holocene and ist interaction with tectonic events. Therefore I'm working on sedimentary sections within the Siwalik Group which are well dated by magnetostratigraphy. I will apply different methods, such as hydrogen and carbon isotopes on alkanes and whole rock geochemistry and mineralogy to constrain weathering rates and intensities. As climate, especially monsoon inetnsity varies laterally, I'm comparing a well-exposed section from the far eastern Himalaya in Aruanchal Pradesh to one in the western Himalayas in Himachal Pradesh. My results I will put in context with already existing data of exhumation rates and if existing erosion rates.
