湘西酒店塘汞矿边深部汞硒锌成矿特征及找矿意义

摘要

酒店塘汞矿位于湘黔汞矿带南端,是以汞为主、共(伴)生硒-锌多金属成矿区.近年来的找矿勘查表明:矿床外围的高寨—上关溪地表以浅发现硒汞矿体,其延深部位找到了大中型汞矿床、硒矿床,硒在矿体中的分布与汞相一致,两者呈正相关关系.而酒店塘矿床边深部出现的锌矿则与汞矿化有明显的分带现象.因此,研究汞-硒-锌的成矿关系及分带现象,对于指导找矿具有十分重要的意义.%Jiudiantang Hg deposit is located at the southern place of Hunan-Guizhou Hg ore belt,which is mainly a Hg deposit,accompanying with Se-Zn polymetallic mineralization in the mining area.The explora-tion and prospecting result in recent years shows that there are Hg-Se orebodies under the shallow surface at Gaozhai-Shangguanxi district in the peripheral of the deposit in which Hg-Se deposit of large-middle scale is also found out in the extended depth.The distribution of Se mineral is consistent with Hg in the orebody,and they are both positively correlated to each other.The zoning phenomenon is obvious between Zn mineraliza-tion outside and in and depth of Jiudiantang deposit and Hg mineralization.Thus,the study of Hg-Se-Zn mineralization and zoning regularity is in great significance to guide the exploration survey of ore deposits in the region.
