摘要
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 orebodies of the exocontact in Antangling Pb-Zn-Ag mine are referred to as the orebodies controlled by the karst, and beside No Ⅰ, Ⅳ, and Ⅴ karst-type orebodies are prognosised in this paper Every group of karst is composed of the upper (from 400 m of 550 m above sea level),the lower (from 200 m to 320 m above sea level) karst rooms and the karst pipe between them (from 320 m to 400 m above sea level), and between two near karsts there is about the distance of 120 m to 150 m According to the halo formed by calcite filling in the karsts in the early stage and the other tectonic signs, karsts can be prognosised in the gallery effectively The prognosic results are consistent with the results of induced polarization anomaly
