Scholars of the Institute of Geology and the University of California-Davis Carried Out Investigation on the Altun Fault

2015/12/29 14:27:05

At the invitation of Researcher Liu Jing, the Deputy Director of State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Prof. Michael Oskin of University of California-Davis and his doctoral student Veronica Prush came to China for exchange visit and cooperative research from August 3, 2015 to September 8, 2015. During this period, together with the team of Researcher Liu Jing, they carried out field investigation in the Suerkal-Pingdingshan section of the Altun fault, and relevant academic exchange in the Institute.

From August 3, 2015 to September 4, 2015, Prof. Michael Oskin, the scientific research personnel of the team led by Researcher Liu Jing and postgraduates in total of nine people carried out joint field survey in the Altun fault area on the border of Gansu, Qinghai and Xinjiang. Their work included detailed mapping of typical geology and physiognomy, identification and division of river terraces, and research on the million-year slip rate of the Altun fault. During the field work, they explored and discussed the issues of common interest in the current research of fault landform, such as field identification and analysis of fluvial fans and river terraces, and identification and classification methods of sectional structures of soil in different landforms. At the same time, they exchange ideas in the method for researching million-year-scale slip rate of the Altun fault through identifying and comparing the lithology of depositional districts and provenance areas.

After the end of the field study, on invitation, Prof. Michael Oskin gave a lecture “Fault system behavior revealed by high-resolution topography” at the geomorphology frontier summer school of Peking University presided over by Prof. Zhou Liping. In order to help other students improve oral English, doctoral candidate Veronica Prush particularly stayed in the Institute of Geology for five days and widely interacted with postgraduates.
