湘黔汞矿带相关成矿问题的讨论

湘黔汞矿带的含汞建造与生油层系的特征相似，汞矿床的形成和油气的聚集一样具有“生、储、盖”的成矿地质条件。中寒武统敖溪组及下寒武统清虚洞组既是汞矿的容矿层，也是汞矿的矿源层。汞的成矿流体是一种以地下水为主、包括油气在内的混合热液，成矿作用是在低温低压高盐度的还原环境中进行的，属于沉积成岩－地下水热液的成因类型。

DISCUSSION OF THE MERCURY MINERALIZATION RELATED TO THE MERCURY METALLOGEIC BELT OF HUNAN GUIZHOU PROVINCE

The Mercury bearing formation of mercury metallogenic belt in Hunan Guizhou Provinces is similar to the characteristics of the oil generating stratsa system.As same as the oil gas congregation,the ore forming geological requirements of "forming,reservos and mantle" were also existed.The host rocks and also the source bed of the mercury deposit are the Aoqi Group of the mid Cambrian and the Qing xudong Group of the low Cambrian.Mercury ore forming fluid is a mixed hydrothermal solution,in which main is the underground water and some oil and gas are included.Mineralization was carried on in a reduction environment of low temperature,low presure and high salinity.The genetic type belongs to the sedimentary rock forming type underground water hydrothermal type.
