Characteristics and Indicators of Gold Deposit in Gold-Bearing Silicon-Iron Formation on Northern Margin of Kunlun Mountains, Xinjiang

The gold deposit in gold-bearing silicon-iron formation has been a characteristic deposit type found in the Kunlun mountains in recent years.Based on detailed geologicalwork, a number of gold ore deposits such as the Paximu,the Ku'a-Qiakenengsayi and the Mate deposits have been successively found in the area.The depositsoccur in theAqiang Formation that is a gold-bearing silicon-iron formation in the marine volcanic eruption-normal clastic deposition foamed in exhalative-sedimentation setting.Regionally, the deposits have clear features of strata-bound ore deposit, which is sinilar to the "Dongfengshan type" in Heilongjiang province.The ore genesis belongs to the type of sedimentary-metamorphic reworking related to volcanic-sedimentary processes.
