江永庵堂岭铅锌银矿床外接触带主矿体属岩溶型矿体 ,本文预测已知Ⅱ、Ⅲ号岩溶矿体的两侧赋存有Ⅰ、Ⅳ、Ⅴ号岩溶矿体。每组岩溶由上、下两个岩厅及廊道组成 ,岩溶组之间的间距约 12 0～ 150m。根据早期充填岩溶的方解石晕并结合其它构造标志 ,能够有效地在坑下预测隐伏岩溶。地质预测结论与物探激电异常结果吻合。
The main ore body outside the contact zone of the Jiangling Nantang Lingling Pb-Zn-Ag deposit belongs to the karst type orebody. It is predicted that there are two types of karstification ore bodies Ⅰ, Ⅳ and Ⅴ on both sides of the Ⅱ and Ⅲ karst ore bodies. Each karst consists of upper and lower rock chambers and corridors. The spacing between karst groups is about 120 ~ 150 m. According to the early filling of karst calcite halo and the combination of other structural markers, it is possible to predict buried karst effectively in the pit. The result of geologic prediction is consistent with the geophysical anomalies.
