Description

The investigations reported here have contributed significantly to the ICDP funded „El'gygytgyn Drilling Project“ in northeastern Siberia. They applied to the 318 m long lake sediment record that was recovered in spring 2009 above a suevite layer in the 3.6 Myr old El´gygytgyn impact crater, with focus on the mass movement deposits that occur incised into the 'pelagic' lake sediments. The scientific expectations of the project were widely fulfilled, namely: (i) the mass movement deposits in the record were identified, (ii) the mass movement deposits were classified and genetically interpreted, (iii) the potentially erosive mass movement events were identified and maximum values for erosion were detected, and (iv) first information concerning the the source areas of mass movement events was obtained. The project thus, firstly, provided fundamental contributions to the unterstanding of gravitational mass movement processes in large lakes. Secondly, it provided important background information for the paleoclimatological investigation of the sediment core that was and will be carried out on the ´pelagic´ sediments within the scopes of other national and international projects.
