The East Kunlun metallogenic belt is an important gold and other metal metallogenic belt in Qinghai Province，but it is mostly concentrated in the eastern part of the East Kunlun.The western part of the East Kunlun not only has a small number of deposits， but also has a small scale of ore deposits.Meanwhile，the research on the genesis of the deposits is weak and the prospecting potential is unknown，which become the bottleneck restricting the breakthrough of gold prospecting in the western part of the East Kunlun.The discovery of Aqiyin gold ore deposit can not only enrich the types of gold deposit in the East Kunlun metallogenic belt，but also have important scientific research value to improve the understanding of gold mineralization rules in the western part of the East Kunlun.The Aqiyin gold deposit is located in the western part of the East Kunlun metallogenic belt，which is a structural ore-control gold deposit occurred in porphyritic quartz monzonite. In order to determine the metallogenic age of the gold deposit，the 40Ar-39Ar age test of sericite in the altered granite-porphyry related to gold mineralization was carried out，and the weighted average ages of sericite are （263.2±4.5）Ma and （268.7±9.7）Ma，respectively. The results show that the main ore-forming age of the Aqiyin gold deposit is the Middle Permian，which is of great significance for further understanding of the genetic mechanism and geodynamic background and regional gold exploration of the gold deposit in the western part of East Kunlun.Meanwhile，enough attention should be paid to whether there is a Middle Permian gold deposit in the East Kunlun area.
