陕西省留坝县营盘一带土壤地球化学特征及找矿方向
|
摘要
研究区大地构造位置位于秦岭造山带南秦岭构造带,属南秦岭晚古生代、中生代金-铅-锌-铁-汞-锑-蓝石棉-重晶石三级成矿带,区域上已在石泉—汉阴北部一带黑色岩系地层中发现多处金多金属矿床。研究区找矿潜力巨大。通过对1∶2.5万土壤测量地球化学分布特征进行分析,对研究区有利的找矿方向进行探讨。研究表明:研究区主攻矿种、成矿有利元素为Au、Mo、Sb、Ag、W;成矿有利地层为舟曲组;成矿有利岩性为含炭板岩、含炭千枚岩(黑色岩系)。
The survey region is located in the south Qinling tectonic belt,and the Late Paleozoic and Mesozoic Au-Pb-Zn-Fe-Hg-Sb-blue asbestos and barite level three metallogenic belts in the South Qinling Mountains.A number of Au polymetallic deposits have been found occur in Shiquan-Hanyin black rock series of strata in northern area of this metallogenic belt.The survey region may have a great prospecting potential.Though analysis of the geochemical distribution characteristics of 1∶25,000 soil surveying,the favorable prospecting direction of the study area was discussed.The result of the study showed that the favorable ore-forming elements in the study area are Au,Mo,Sb,Ag,W,the favorable ore-forming formation is the Zhouqu Formation,the favorable lithology of mineralization is carbon-bearing slate and carbon-bearing phyllite(black rock series).
