本区是在我国北方寻找含锡多金属矿产资源的一个远景区.由于大部地区为黄土覆盖,地质构造又复杂,研究程度较低.以前虽投入过一定的地质、物化探找矿工作,但一直未取得大的突破.1983年在该区投入了以电法为主的新仪器方法试验和综合找矿工作,取得了显著的找矿效果.对新发现的IP异常进行了综合评价和定性解释,并对其中可能为矿异常的IP_2异常进行了定量解释和钻孔深部验证.验证结果,不仅设计的7个钻孔都见矿,而且每孔实际见矿深度范围和矿体品位,基本上均与预期结果吻合.实践表明,对于寻找这种地表无矿化,化探异常不明确,磁法无反应,有一定埋深的隐伏矿床,I P法具有独特的找矿效果.下面对所取得的结果作一简介. 地质概况及物性特征
This area is a prospective area to search for tin-bearing polymetallic mineral resources in northern China.As a result of loess cover in most areas, the geological structure is complicated and the degree of research is relatively low.Although some geological, geophysical and geochemical prospecting work has been put into operation in the past, But no major breakthrough has been made. In 1983, a new instrument method test and integrated prospecting mainly based on electric method were put into this area and significant prospecting results were achieved. The newly discovered IP anomalies were comprehensively evaluated and Qualitative interpretation and IP_2 anomaly which may be mine anomalies were quantitatively explained and verified by deep drilling.As a result of verification, not only all the 7 boreholes were designed, but also the mine depth range and ore body grade were actually found in each hole, Which are basically in line with the expected results.Practice shows that the IP method has a unique prospecting effect for the purpose of finding a hidden deposit with no buried mineralization, anomalous geochemical anomalies, no reaction by magnetic method and a certain buried depth. A brief introduction of the results obtained.Geological overview and physical characteristics
