【摘要】 文章从解析已知矿体入手 ,认为江永铅锌矿床外接触带主矿体不是脉型矿体 ,而是岩溶型矿体。岩溶成矿构造受石磴子组中厚层灰岩控制。一组岩溶由两个岩厅组成 ,一个发育于 2 0 0～32 0 m标高 ,另一个发育于 4 0 0～ 550 m标高。根据近等距性原则 ,分别于已知岩溶型矿体 ( 、 )的南、北两侧预测了 、 及 号岩溶组。建立了岩溶成矿构造系列、结构及坑下鉴别标志 ,并探讨了岩溶的形成与演化。预测结论与物探激电异常结果吻合。更多还原

【Abstract】 Studies of known orebodies, the main orebodies of exocontact imply that the orebodies are Karst type rather than vein type in Jiangyong Pb Zn mine. Karst metalotectonics are controlled by medium thick bedded limestone of Shidengzi Formation. A group of Karst is composed of two Karst rooms of which one develops between 2oo m and 320 m level, and another forms between 400 m and 550 m level. According to near isorange principle, No. Ⅰ,Ⅳ and Ⅴ karsts are prognosised on the south side and the north side of known Karsts (Ⅱ、Ⅲ).Karst metalotectonic series,its structure and its distinct signs in the gallery have been established in this paper. The prognosic results are consistent with the results of induced polarization anomaly.更多还原
