| 摘 要： | 湘西黔东汞铅锌矿床是在区域汞铅锌初始丰度较高的矿源层基础上和断裂构造的驱动下,经加里东期封存热卤水改造形成。成矿溶液具有低温度、高矿化度、高盐度和含有机质等特点,其组分为Na(K)-Ca-Cl型。构造条件为其环流系统,亦是矿体赋存场所。矿床属沉积-热卤水改造成因。

| Abstract: | Mercury-lead-zinc deposits in western Hunan and Eastern Guizhouresult from a regional soucre bed, with comparatively high initial abundanceof Hg, Pb and Zn, reformed by the pent-up caledonian hot brine throughfractures. The oreforming solution is characterized by low temperature,high mineraliz ation intensity, high salinity and organic-matter bearing,andis of Na(K)-Ca-Cl type in composition. The structural environment givesrise to the circulation system and the depositing site of orebodis. Thedeposits belong to sedimentary-hot brine reformational type. |
