摘　　要：古丈县万岩重晶石矿点是开展湖南古丈地区矿产地质调查过程中新发现的矿点。本区重晶石矿属低温热液型矿床,成矿完全受裂隙控制。矿体主要赋存于震旦系上统金家洞组(Z2j)地层中,该地层中部的磷矿和底部的黄铁矿均在野外易于识别,且与重晶石矿体有着较为密切的空间关系,对找矿有着重要的指示作用。万岩重晶石矿点以东地区具一定的找矿前景。Wanyan Barite Ore point in Guzhang is newly discovered mineralization point when carry out Hunan Guzhang region mineral prospective survey. The genesis of the deposit can be speculated as low temperature hydrothermal deposit. The Ore genesis are complete controlled by fissure. The ore-bearing stratum is early Sinian System Jinjiadong Group（Z2j）,the phosphorite in middle part of this stratum and the pyrite in the bottom of the same stratum is easily identified in field observation and the consanguineous spatial relationship with Barite Ore body has important indicator for prospecting. Its east there may be a certain size of ore body with some prospecting prospect.
