Sedimentology and stratigraphic framework and implications for lake level changes and paleoseismology
As a closed lake basin, Lake Van reacts very sensitively with lake level changes to any alterations of the hydrological regime in response to climate change and tectonic activities. The sedimentology and site-to-site correlation of the drilled sedimentary sections will yield the stratigraphic framework, providing the sedimentological response of the Lake Van as dynamic system to the environmental forcing. High-resolution sediment trap techniques will be applied to define and calibrate the seasonal dynamics of modern varve formation. Comparison with lithologies of ancient varves will provide insights into seasonal cycles for the Holocene and former interglacials. The record of earthquake-induced microdeformation structures will furthermore establish a paleoseismic event catalogue reflecting past tectonic activity in the area.
