| 摘 要： | 通过对贵州晴隆县大厂矿田西部普晴锑金矿区的成矿地质特征及自然景现条件的调查研究.认为该区为中高山湿润剥蚀景观区,适合开展沟系土壤测量.通过方法实验,提出了沟系土壤测量的关键技术指标,即:采样介质为沟系两侧残坡积物、冲刷物,采样层位为B层;采样密度为30-50个/km2,样品加工粒度为20目.利用STASTIC软件对测试数据的常用对数值进行R型因子分析,得到4个F因子组合,圈定了3个异常区.根据对元素异常下限值及F因子组合异常的评价分析,筛选出3个Sb、Au找矿靶区,可作为下一步地质找矿的依据.

| Abstract: | Based on geology and nature landscape in the Puqing Sb-Au orefield in the western Dachang ore district of Qinglong country,it is founded that the area belong to secondary mountain humid sight district of denudation,and soil geochemistry measurement of drainage system for ore prospecting can be conducted.Through method experiments,the key technical rule of soil geochemistry measuring in drainage system has been put forward.Sampling targets are talus and scour materials in two sides of drainage system,and sam... |
