Abstract: The 1∶50 000 scale geological and mineral survey has been conducted in Langqin Region of Tianjun County, Qinghai Province. Based on regional geological survey, measurement of stream sediment, and remote sensing interpretation and alteration information extraction, the project carried out rough exploration and anomalous verification of geophysical and geochemical survey, with comprehensive utilization of previous regional geology, geophysics, geochemistry, remote sensing, mineral and other information. The metallogenic geological background and metallogenic conditions of copper, gold, silver, vanadium, chromium, nickel and other minerals in the study area were basically found out. Meanwhile, 45 stream sediment single element anomaly sites were identified, including 31 class B anomalous sites, 14 class C anomalous sites and 4 newfound metal ore (mineralized) points. The regional metallogenic prospection areas were identified and prospecting directions for minerals were also pointed out.
