摘　　要：三江河村锰矿区位于广西北部,具有勘查新元古代锰矿的潜力。通过开展地质找矿工作,发现矿区震旦系陡山沱组(Z d)原生沉积形成碳酸锰矿矿胚层,浅表形成次生氧化锰矿层,总结了氧化锰矿的成因规律与找矿标志。经过对比研究与综合分析,认为矿区可以往北继续追索氧化锰矿体,矿床规模可达到小-中型,指出震旦系陡山沱组(Z d)浅表氧化锰矿具有较好的找矿前景,靠近湖南、贵州等含锰盆地,在南华系富禄组(Nh f)取得找矿成果的可能性也较大。The Sanjiang Hecun manganese deposit area,located in northern Guangxi,exhibits significant potential for Neoproterozoic manganese exploration.Geological investigations revealed that the Sinian Doushantuo Formation(Zd)hosts primary sedimentary manganese carbonate protoliths,with secondary manganese oxide ore layers formed in shallow oxidation zones.Genetic patterns and prospecting indicators of manganese oxide deposits were systematically analyzed.Comparative studies suggest that the manganese oxide ore bodies can be traced northward,potentially forming small-to-medium scale deposits.The study demonstrates that shallow oxidized manganese deposits in the Sinian Doushantuo Formation(Zd)possess favorable prospecting potential,while the Nanhua Fulu Formation(Nhf)near manganese-bearing basins in Hunan and Guizhou provinces also shows substantial exploration promise.
