××背斜位于黔西南兴仁、贞丰县境内。一九八一年,我队在背斜中段开展汞矿普查时,采样做金分析,发现有的样品金含量已达工业品位。 经鉴定,金矿中的金呈微细粒侵染型,肉眼不可见。矿体与围岩无明显界线。 为扩大及加速对××背斜含金性评价,一九八二年八月至八三年底,完成了12.6平方公里1:1万金矿土壤测量的化探工作。所圈定的Au异常经挖槽验证,见矿率达63.3％。同
× × anticline is located in Qianxinan Xingren, Zhenfeng County. In 1981, when conducting a mercury mine census in the middle of the anticline, our team sampled the gold samples and found that the gold content of some samples reached the industrial grade. It has been identified that the gold in the gold mine is fine-grained and invisible to the naked eye. No obvious boundary between ore body and surrounding rock. In order to expand and speed up the evaluation of the gold content of the XX anticline, geochemical exploration of the soil survey of 1: 10,000 gold mine of 12.6 square kilometers was completed from August 1982 to the end of 1983. The delineation of the Au anomaly verified by the trenching, see mine rate of 63.3%. with
