| 摘 要： | 通过对石柱子花岗闪长岩体重砂爆裂法研究，发现其轻组分爆裂频次（或活度）有明显差异．并确定区内重砂轻组分爆裂颇次异常下限值为４２００次，据此确定了８个重砂爆裂活度异常区，圈定并缩小了找矿靶区。同时重砂爆裂普查法还可以反映出岩体成矿的可能性，判别岩体的矿化程度．研究表明，重砂爆裂普查法对于发现热液盲矿体具有可行性，可为普查找矿提供信息．

| Abstract: | The studies on the application of placer decrepitation reconnaissance method in prospecting copper in the granodiorite rockbody of Shishzi show that the decrepitation frequencips(or activities)of fight components are obviously different,which the lowest limit is 4200 and there are 8placer decrepitation activity anomalous zones,then ore prospecting taget areas are outlinde and reducde. The results of the method not only can indicate the posibility of a rockbody.but also its degree of mineralization.As a result,the method is teasible for prospectins hydrothermal blind orebodies and can provide information for reconnaissance surveying and ore prospecting. |
