摘　　要：贵州松桃李家湾—杨立掌锰矿床矿体产于南华系中统大塘坡组第1段黑色炭质页岩底部,平均厚2.78 m,平均品位19.45%,埋深0~2300 m,呈层状、似层状产出,属典型的“大塘坡式”锰矿床。矿床产于南华纪大塘坡早期武陵次级裂谷李家湾—高地—道坨IV级地堑盆地中,目前矿床所控制的矿体均位于锰矿古天然气渗漏沉积成矿系统中的过渡相和边缘相位置,中心相主体尚未完全揭露,矿床深部具有较大的找矿潜力。Pine peach lijiawan-Yanglizhang manganite deposit body is produced in the South China mid-tongpo group.The first section of black charcoal shale bottom is of average thickness of 2.78 m,average grade of 19.45%,with its buried depth of 0 to 2300 m in a layered,layered output.It is a typical“Datangpo type”manganese deposit.The deposit was produced in Lijiawan basin,and it is in the early Wuling sub-rift of the Datangpo in the South China Period.The ore body controlled by the deposit is currently located in the transition phase,including the edge phase of the manganese mine ancient natural gas leakage sedimentary deposit position.The main body of the central phase has not yet been fully revealed and the deep part of the deposit has a large ore prospecting potential.
