Abstract:

The study area is located at the join position between the eastern Kunlun and the West Qinling,which experiences a complex tectonic evolution,consists of the Lower Triassic Longwuhe Group strata mainly,and outcrop mediate-acidic magmatic rocks,but the tungsten mineralization did not been discovered before.The Xianlonggou antimony-gold deposit and the Jiawu gold deposit have been discovered un the area,it displays a good geological metallogenic condition.The primary data of 1∶50 000 stream sediments suggest that it enriches the W,Au,Ag,As and Sb elements in the area.Analyzing the geological and geochemical characteristics and the regional metallogenic conditions,combining with the actual prospecting work,all these indicate that the Xiaoqurugou-Jiarihai mine has better tungsten-forming potential.As mentioned above,we propose that the tungsten anomalies are the first precondition and the favorable object for the tungsten prospecting,which is predominated by the alteration rock and quartz vein type mineralization,the medium-thin sandstones and the thin sandstone inter-layers within slate,which belong to the second rock department of  the Longwuhe Group.

Key words: geological and geochemical characteristics, tungsten ore, potential analysis, Qinghai Province
