Tim Cope - Tectonics of NE China

Research Description:

My research centers on the tectonic development of northeastern China during the assembly of Asia. The Asian continent is composed of numerous continental fragments and volcanic islands that collided with each other over the course of the last 270 million years. The most recent manifestation of this process is the collision of India with Asia, which has uplifted the Himalayan mountain range and the Tibet plateau, collectively known as the "roof of the world". The India-Asia collision has also triggered the uplift of numerous mountain ranges in Asia that are distant from the collision zone itself, such as the Tian Shan, Kunlun Shan, and Hindu Kush. Northeast of Beijing, in the rugged terrain traversed by the Great Wall, lies an ancient mountain range that was roughly analogous to these distant collisional mountain ranges. The Yanshan fold-thrust belt represents the eroded remains of a once-great mountain belt that developed as a result of at least three separate collisional events. The work of my research group has been to establish the ages of multiple uplift and deformation events in this region, in order to better understand the processes involved in the assembly of Asia and the long-term effects of continental collision. The methods our group has employed over the years include geologic field mapping (we climb mountains in the Yanshan belt and look at faulted and folded rocks to establish their ages relative to regional tectonic events), stable isotope methods (analyzing the oxygen-isotope content of ancient soils can yield information about climate and elevation), and radiometric dating (certain rock types can be dated using radiometric isotopes as a "clock").
