Geologic Characteristics of the Kaerqueka Porphyry Copper Deposit in Qinghai Province and Its Prospecting Significance

Kaerqueka copper-polymetallic deposit is one of the large copper-polymetallic deposits,it was found in the western part of the East Kunlun metallogenic belts in recent years.Early during the skarn-type ore prospecting,it was discovered porphyry mineralization information,and in the recent years,porphyry mineralization is becoming clear.Through the analysis of distribution and deep cross-section of the Late Triassic porphyry,it displayed that the porphyry body is a duplex of little rock strain.The petrochemical and geochemical characteristics of the granodiorite porphyry and associated quartz diorite has been common with that of adakitic rocks,indicating that the mineralization tectonic environment is related to the eastern Kunlun Mountains-Late Triassic magmatic underplating,and has good prospects for exploration,expanding the direction of prospecting of the ore belt in East Kunlun.
