Abstract
The Jiangligou tungsten polymetallic deposit is the largest tungsten deposit in Qinghai at present,which has reached a medium-large deposit scale.It is structurally located at the west Qinling orogenic belt of Qinling-Qilian-Kunlun composite orogenic system.This work summarized the ore-controlling factors and mineralization enrichment regularity of this deposit based on the metallogenic geological setting,geological characteristics,orebody characteristics.The orebodies are controlled by the contact zone between the Gangcha composite granite body and the surrounding rocks.The mineralization shows significant vertical zonation around the rock mass,i.e.,porphyry type molybdenum,greisen type tungsten,skarn type copper-wolfram-molybdenum,hornfels type tungsten and hydrothermal vein lead-zinc from the granite body to surrounding rocks,and the dominate type is skarn type.The genesis of deposit is multinity which related to the intrusion of late stage granite porphyry and fine-grained granite of the Jiangligou composite granite in Late Triassic and late magmatic hydrothermal solution.This work may provide basis for the next step prospecting.关键词
