东昆仑日吉普顶石英斑岩体含金性及其与黑山地区砂金关系探讨

Relationship between Rijipuding quartz porphyry body gold-bearing,East Kunlun and placer gold in the Heishan region,Xinjiang

东昆仑黑山地区分布有多处砂金矿,但是岩金找矿没有重大突破,2009年吉林省地质调查院在黑山地区日吉普顶一带发现了具全岩金矿化的石英斑岩体,作者论述了石英斑岩体的含金性,黑山地区砂金的分布特征,特别强调了晚更新世晚期地壳活动相对稳定期冲-洪积层的形成及砂金成矿作用,探讨了日吉普顶含金石英斑岩体与黑山地区砂金矿的物源关系。

There are many placer gold deposits in Heishan area of East Kunlun,but without major breakthrough in rock gold prospecting.The quartz porphyry body with whole-rock gold-bearing was discovered by Institute of Geological Survey of Jilin Province in Heishan area in 2009.The authors discussed the gold-bearing characteristics of quartz porphyry and the placer gold distribution characteristics in Heishan area,especially emphasized the formation of alluvium-diluvium and the placer gold metallogenic process in the later period of late Pleistocene in relatively stable crustal activities,and discussed the relationship between Rijipuding quartz porphyry body gold-bearing,East Kunlun and placer gold in the Heishan region,Xinjiang.
