新疆托里县阿克塔木金矿区原生晕垂直分带研究

Study on Vertical Zoning of Primary Halo in Aketamu Gold Mining Area,Tuoli County,Xinjiang

新疆托里县阿克塔木金矿区位于达拉布特—卡拉麦里铬金成矿亚带,是一个重要的金矿化集中区。河南省地质矿产勘查开发局测绘地理信息院在区内进行了大量勘查工作,本次研究应用格里戈良分带指数法对以往地质工作中的岩石化探分析结果进行处理分析,对Au、Ag、Cu、Pb、Zn、As、Sb、Bi、W、Mo、Sn共11个元素进行垂直分带排序,得出新疆托里县阿克塔木金矿区原生晕垂直分带序列,通过与中国金矿床原生晕综合轴(垂)向分带序列的对比分析,推断矿区深部仍有盲矿体存在,深部找矿潜力较大。

The Aktamu gold mining area in Tuoli County,Xinjiang is located in the Dalabute-Karamaili Chromium-Gold mineralization metallogenic subbelt,which is an important gold mineralization concentration area.The Institute of Surveying,Mapping,and Geographic Information of the Henan Bureau of Geology and Mineral Exploration and Development has conducted a large amount of exploration work in the region.This study applies the Gregorian Zoning Index method to process and analyze the results of geochemical exploration and analysis of rocks in previous geological work.A total of 11 elements,including Au,Ag,Cu,Pb,Zn,As,Sb,Bi,W,Mo,and Sn,are vertically zoned and sequenced to obtain the vertical zoning sequence of primary halos in the Aktamu gold mining area,Tuoli County,Xinjiang.By comparing analysis of the comprehensive axial(vertical)zoning sequence of the primary halo of gold deposits in China,it is inferred that there are still blind ore bodies in the deep part of the mining area,and the deep prospecting potential is large.
