摘　　要：共青湖锰矿床与铜锣井大型锰矿床、深溪大型隐伏富锰矿床同位于深溪-八里Ⅲ级地堑盆地中,含锰岩系为茅口组第三段,锰矿体位于含锰岩系下部,矿体埋深800~450 m,锰矿体厚度小但较稳定,一般为0.8~0.9 m,Mn平均品位为16.62%,目前深部矿体尚未圈边。通过对共青湖锰矿床地质特征分析,认为其属“气液喷溢沉积型”锰矿床,总体位于成锰过渡相中,显示该区深部有较大找矿潜力。Gongqinghu manganese deposit,along with Tongluojing large manganese deposit and Shenxi large concealed manganese rich deposit,is located in Shenxi Bali III level graben basin.The manganese bearing rock series is the third section of Maokou Formation and the manganese ore body is located in the lower part of the manganese bearing rock series.The depth of the ore body is 800~450 meters and the thickness of the manganese ore body is small but relatively stable,generally 0.8~0.9 meters.The average grade of Mn is 16.62%.Currently,the deep ore body has not been surrounded.Through the analysis of the geological characteristics of the Gongqinghu manganese deposit,it is believed that it belongs to the“gas-liquid overflow sedimentary type”manganese deposit.The entire area is located in the manganese transition phase.It shows that there is great prospecting potential in the depth of the area.
