| 中文摘要: |
| 碧江长行坡锰矿床位于南华纪万山中朝溪-盆架山-长行坡IV级地堑盆地中。该地堑控制形成了长行坡、盆架山、中朝溪、洪岩洞及湖南莫家溪等中小型锰矿床。矿床具体处于区域瓦屋向斜南西段，构造线总体呈NE向展布，锰矿赋存于南华系大塘坡组第一段底部黑色炭质页岩中，呈层状、似层状大致顺层产出，含矿层内部结构较简单，一般为1层矿。矿石矿物以菱锰矿、钙菱锰矿为主；矿石具泥晶、砂屑等结构，条带状、块状构造。矿床成因类型为古天然气渗漏沉积型锰矿床。 |
| 英文摘要: |
| Changxingpo manganese deposit is located in Zhongchaoxi-Penjiashan-Changxingpo IV graben basin of Wanshan in Nanhua period.This graben controlled and formed Changxingpo，Penjiashan，Zhongchaoxi，Hongyandong，Mojiaxi in Hunan and other small manganese deposit.The deposit situated in SW Wawu syncline，the structural line distributed NE generally，the manganese occurred in the bottom black culm of the 1st section Datangpo formation，Nanhua system bedded and stratoid，the inner structure of ore-bearing strata is simple，the strata is single generally.The ore mainly are rhodochrosite and ropperite with the structure of micrite，arene，stripped and massive.The deposit genesis is ancient natural gas seepage sedimentary manganese deposit. |
