摘要
Qinling, Qilian and Kunlun orogenic belts were formed by the superimposition of paleo-Asian and Tethys structural domains, which had played an important role in the formation of China’s continent during Phanerozoic. Based on studies of the ore-forming events of Qinling, Qilian and Kunlun orogenic belts in relation to their structural environments, the authors have found that the main metallogenic events correspond to specific structural responses. Accordingly, the paleo-Proterozoic Bulunkou magnetite deposit in West Kunlun might have been an important iron formation event. The Qimantage ore concentrated area located along the convergence zone between Altun and East Kunlun tectonic belts is a main tectonic syntaxis.
