Geological Characteristics and Controlling Factors of Tungsten Polymetallic Mineralization in Zakong Longwa Area,Dulan County,Qinghai Province
The study area is located in Berkarik-Chantilly Indosinian period metallogenic belt in the eastern part of the East Kunlun orogenic belt,and the geophysical and geochemical anomalies in the area show a good metallogenic prospect.In the process of anomaly verification,six gold and silver bearing structural alteration belts were found,including 8 deposit ore bodies and 1 gold and silver ore body.According to the analysis,the minerals in the area were formed under the control of regional structure,magmatic rocks,strata and other comprehensive factors.When the carbonate sedimentary formation encountered high temperature fluid,strong gas-aqueous metasomatism oc-curred.The mineralization stages were mainly the progressive metamorphic stage,the retrometamorphic stage and the oxide stage,and the quartz-sulfide stage was divided into early sulfide stage and late sulfide stage.
