摘要
冯家湾锰矿位于黔北裂谷盆地锰矿区内遵义-黔西锰矿成矿带,属于遵义锰矿成矿亚带的深溪-八里锰矿带,遵义锰矿主要分布在该锰矿带内,位于冯家湾Ⅳ级地堑盆地沉积中心位置.埋藏深度为0～557 m,矿体赋存于二叠纪茅口组第三段,Mn平均品位为13.69％,平均厚度为1.37 m;研究区内浅部为氧化锰矿石,深部为碳酸锰矿石,碎屑状、鲕状和块状构造.通过对冯家湾锰矿地质特征分析,认为其属于典型的"气液喷溢沉积型"锰矿床,位于成锰中心边缘,显示具有较大的找矿潜力.
Abstract
Fengjiawan manganese ore is located in Shenxi-Bali manganese ore belt of the Zunyi-Qianxi Manganese Ore Ore Orogenesis Belt,which is a sub-belt of Zunyi Manganese Ore Orogenesis Belt in the north Qianjiang Rift Valley Basin Manganese Orogenic Region.Zunyi Manganese Ore is mainly distributed in this manganese ore belt,and it is located in the sedimentary centre of the Fengjiawan Ⅳ rift valley basin.The depth of burial is 0～557 m,and the ore-body is located in the third section of the Permian Maokou Formation,with an average Mn grade of 13.69％and an average thickness of 1.37 m.In the area,there are manganese oxide ores in the shallow part and manganese carbonate ores in the deep part,and the structure of the ore body is crumbly,oolitic and blocky.In analysing the geological characteristics of Fengjiawan manganese ore,this paper believes that it is a typical"air-liquid overflow sedimentary"manganese ore deposit,which is located at the edge of the manganese-forming centre.It has a large potential for finding minerals.
