摘要
一、地层岩石与矿床关系本矿区的区域地层很简单,除第四纪冲积层外,仅有下部古生代岩层,下寒武系与中、上寒武系局部为假整合接触,寒武系与奥陶系为整合接触,下奥陶系与中奥陶系为假整合接触,奥陶系与志留系为整合接触。大区内无火成岩分布。
There is a zone of telethermal type of lead-zinc deposits in Certain district ofHunan. The ore-bearing formation is a limestone of Cambrian age. The structural significanceis manifested by a series of northeast running anticlines which are the favorable localitiesfor the concentration of lead-zinc deposits. The mineralogical composition of these depositsis very simple, chiefly composed of galena, sphalerite and calcite with some chalcopyrite,pyrite, siderite, cinnabar, dolomite, barite, quartz, fluorite occasionally.
