Recently,the Institute of Geology held a field seminar on the Qilianshan Orogenic Belt in Xining to deepen fundamental geological survey and research on the Qilianshan Orogenic Belt, providing a platform for sharing research results and interdisciplinary knowledge. Over 50 experts and graduates attended the seminar and they are from the Tianjin Center of China Geological Survey,Qinghai Geological Survey Institute,Gansu Geological Survey Institute,Northwest University,Hefei University of Technology,the Institute of Geology, CAGS,and the Institute of Geomechanics, CAGS.They traveled across northern,middle, and southern Qilian landmass in six days, covering over one thousand kilometers, and had an in-depth interdisciplinary discussion.

Researchers Zhang Jianxin and Yan Zhen described in detail the fundamental geological setting of the study area and the planned investigation routes, observation targets, important geological phenomena, research results and scientific significance. They also systematically reported their latest research achievements respectively,including Early Paleozoic subduction-related high pressure/low temperature metamorphic rock series(blueschist,eclogite), ophiolite suite,melange, and related basins (island arc,fore-arc,back-arc)and marine/continental sedimentary-volcanic formation.

Present at the seminar are experts and graduates in engaged in such research fields as metamorphic petrology,sedimentary geology,structural geology,magmatic petrology,and regional geology. They put forward a new thought on the study of orogenic belts, holding that research on the stratigraphic age,structural environment andstratigraphy of orogenic belts plays a crucial role, and reached a consensus that further research on fundamental geology such as stratigraphy is needed to clear up the bottleneck in mineral prospecting in the study area.

In the field seminar,geologists with different professional backgrounds shared their achievements and practice in geological survey of various projects. They learned from and inspired each other.By doing so, they deepened understanding of geological issues, which is favorable to fundamental research on the Qilianshan Orogenic Belt with such a complex geologic structure.
