东天山成矿带中段化探普查工作方法与找矿效果
|
摘要
在研究区开展的1∶5万化探工作统一采用土壤测量,采样粒级-4～+20目,能很好反映采样单元内的地质背景特征,多点组合的采样方法提高了样品的代表性。在取得可靠化探数据的基础上,采用元素含量与规模(面积大小)两个约束条件,圈定了一批有找矿前景的异常。通过开展异常查证,取得了良好的找矿效果,开拓了研究区的找矿空间。
1:50 000 geochemical prospecting work unified use of soil survey in study area,sampling grain size-4～+20 mesh,Geological Background Characteristics are well responded,It also greatly improves the representativeness of samples.On the basis of obtaining reliable geochemical data,two constraints of element content and size are adopted,a number of anomalies with prospecting prospects have been delineated.Outcome of anomaly delineation,take the opportunity to carry out abnormal verification work,good prospecting results have been achieved,opening up prospecting space in the study area.
