TeBi Research would like to welcome one of its overseas collaborators Prof. Yan Zhen, who is visiting for 3 months!
Prof. Yan is working on the hotly disputed tectonic evolution of the Qinling and Qilian orogenic belts in China. In these belts numerous different tectonic models have been proposed and this has added to confusion in understanding of this area. Complexity results from the long history of the evolution of proto-Tethyan Ocean, which has been deciphered from mainly isotopic and geochemical data, with rare fossil occurrences. Prof. Yan wishes to learn more about the rock assemblages and associated fossils to help reconcile these with tectonic events.
