- Abstract:
- Metallogenetic units show regional mineralization setting and regularity, and are the foundation of mineral prospecting, exploration and prediction assessment. According to the demand for mineral prospecting and exploration, based on the former’s research achievement, in terms of regional tectonic evolution and mineralization regularity of stratigraphy, tectonic, magmatic belt and associated mineral, the metallogenic units in Qinghai were classified systematically, complicatedly and uniquely. The classification of metallogenetic units include 2 Ⅰ-grade metallogenic domains of Qin-Qi-Kun and Tethyan, 6 Ⅱ-grade metallogenic provinces of North Qilian, Qaidam Basin, East Kunlun, the western of West Qinling, Hoh Xil-Bayan Har and the westward extension of North Sanjiang, 16 Ⅲ-grade metallogenic belts and 41 Ⅳ-grade metallogenic subbelts. And then, the mineralization condition, dominant minerals and deposit types of Ⅲ-grade metallogenic belts and Ⅳ-grade metallogenic subbelts were analyzed in order to find the mineralization regularity and provide prospecting direction and metallogenic prediction in Qinghai.
