发布时间：2019-02-27 17:47
【摘要】：大巴山地区跨秦岭、扬子两个一级构造单元,基于1:5万水系沉积物测量成果,统计计算了成矿元素地球化学参数,分析研究了元素分布特征、元素相关性及异常元素组合特征,认为研究区Pb、Zn、Ba、Cu、Mn找矿潜力较大,推断研究区所在的秦岭构造单元成矿类型主要为与震旦系—下寒武统黑色岩系有关的低温热液锌铜矿和沉积型钡矿;研究区所在的扬子构造单元成矿类型主要为与寒武系碳酸盐地层有关的低温热液铅锌矿和与震旦系碳酸盐岩有关的沉积型锰矿;在此基础上,划分出杨家坪—葛洞钡锌成矿远景区、镇坪钡锌成矿远景区、黄安坝—迷魂阵锌铜成矿远景区、百羊坪铅锌成矿远景区和修齐镇—石坊乡锰成矿远景区。
[Abstract]:Based on the results of 1: 50 000 stream sediment survey, geochemical parameters of ore-forming elements are calculated statistically and the distribution characteristics of elements are analyzed and studied in Dabashan area, which are two primary tectonic units across Qinling and Yangzi. The correlation of elements and the characteristics of abnormal element assemblage indicate that the prospecting potential of Pb,Zn,Ba,Cu,Mn in the study area is great. It is concluded that the ore-forming types of Qinling tectonic unit in the study area are mainly low-temperature hydrothermal zinc-copper ore and sedimentary barium ore related to the Sinian-Lower Cambrian black rock series. The metallogenic types of Yangtze tectonic units in the study area are mainly low-temperature hydrothermal Pb-Zn deposits related to Cambrian carbonate strata and sedimentary manganese deposits related to Sinian carbonate rocks. On this basis, it is divided into Yangjiaping-Gedong barium-zinc metallogenic prospect, Zhenping barium-zinc metallogenic prospect, Huanganba-ecstasy zinc-copper metallogenic prospect, Baiyangping lead-zinc metallogenic prospect and Xiuqi town-Shifang township manganese metallogenic prospect.
