摘　　要：本文研究总结了桂阳县六合矿区六合锰矿控矿地质条件、分布特征、矿床成因及找矿标志。认为矿床受地层与构造叠加控矿,当冲组上部海相硅质层中富含锰,为锰矿的形成提供了物质来源,当冲组下部瘤状灰岩与栖霞组不纯灰岩在构造应力下形成层间破碎,为上覆的锰物质往下迁移提供了沉淀富集的场所。This paper studied and summarized the ore⁃controlling geological conditions,distribution characteristics,genesis and prospecting criteria of Liuhe manganese deposit in Liuhe Mining Area,Guiyang County.It is considered that the deposit is controlled by stratigraphic and structural superposition.The marine siliceous layer in the upper part of Dangchong Formation is rich in manganese,which provides material source for the formation of manganese ore.The nodular limestone in the lower part of Dangchong Formation and impurity limestone in Qixia Formation form interlayer fracture under tectonic stress,which provides a place for precipitation and enrichment of the manganese material in the upper part of Dangchong Formation.
