| 摘 要： | 连城坪上银矿体呈似层状、透镜状产于近东西向、北西向、北东向断裂破碎带中,可分为中温、中低温和表生期3个成矿阶段,其中中低温绿泥石化、硅化、绢云母化、黄铁矿化等矿化蚀变与矿体密切相关,成矿热液推测为燕山期岩浆期后热液,矿床受构造控制,属构造破碎带岩浆期后热液充填交代型银矿床。

| Abstract: | The Pingshang silver orebody in the Liancheng county exists as a quasi-layer and lentic- ular, which is controlled by the faulted structures with the closed east-west trend, east- northeast and the west-northeast trend. The deposit can be divided into three metallogenic stages of medium temperature, medium-low temperature and supergene period. Mineralized alteration of chloritization, silicification, sericitization and pyritization have a close relation with the orebody. Hydrothermal fluid is presumably Yanshan period magmatic fluid and the deposit is controlled by the structures. It belongs to the tectonic fracture zone post magmatie hydrothermal filling metasomatic deposit. |
