摘要
位于贵州遵义国家锰矿整装勘查区内的复兴隐伏富锰矿床,埋藏深度达1300~1550 m,矿体赋存于二叠纪茅口组第三段,Mn平均品位为18.01%,平均厚度为2.12 m;矿石矿物以菱锰矿为主,局斑杂状、浸染状和块状构造。通过对复兴锰矿床地质特征分析,认为其属于典型的“遵义锰矿内生外成气液喷溢沉积型”锰矿床,位于茅口晚期深溪IV级地堑盆地内深溪-复兴成矿带的成锰边缘相,其北部为成锰中心相,显示具有较大的找矿潜力。
Fuxing concealed manganese rich deposit is located in Zunyi National Manganese Ore Packaged Exploration Area,Guizhou,with a burial depth of 1300~1550 m.The ore body occurs in the third member of Maokou Formation in Permian,with an average Mn grade of 18.01%and an average thickness of 2.12 m.The ore minerals are mainly rhodochrosite with local mottled,disseminated and massive structures.In the analysis of geological characteristics of Fuxing manganese deposit,it is considered that it belongs to the typical“Zunyi manganese ore endogenetic exogenetic gas-liquid exhalation sedimentary type”manganese deposit,which is located in the manganese forming marginal facies of Shenxi Fuxing metallogenic belt in the late Maokou Shenxi IV graben basin.And the northern part is the manganese forming central facies,which shows great prospecting potential.
