1960年在南风山发现—自电异常,异常两侧控制钻孔均未见矿,而推断为过滤电场引起.1966年又做了激发电位法(用中间梯度方式工作),在自电异常处发现有异常与之重迭.布置了Ck703、Ck702、Ck701三个验证孔,前两孔于浅部见炭质灰岩,并分别在220米、460多米处见到矿体,后一孔只见强烈矿化.对验证结果有三种不同的看法:一种认为“异常由浅部炭质灰岩引起,深部见矿只是偶然巧合”;另一种认为是“不论是什么原因引起的,总算打到了矿”;第三种认为“异
Found in the southern windy mountain in 1960 - self-anomalies, abnormal control of both sides of the control holes were not found in the mine, and infer that the filter caused by the electric field .1966 also made the excitation potential method (using an intermediate gradient mode) Abnormalities were found overlapping with the three verification holes Ck703, Ck702 and Ck701, the first two holes in the shallow see carbonaceous limestone, respectively, at 220 meters, 460 meters to see the ore body, the latter hole I saw strong mineralization. There are three different views on the verification results: one is that ”the anomaly is caused by shallow carbonaceous limestone, the mine is only by accidental coincidence“, and the other is ”whatever the cause , And finally hit the mine “; the third that ” different
