| 中文摘要: |
| 贵州松桃普觉超大型锰矿床受南华纪普觉Ⅳ级地堑成锰盆地控制，由于同沉积断层作用，两界河组、含锰岩系、锰矿体、大塘坡组第二段、南沱组等地层均从南往北由薄变厚，盆地中存在2个呈NE65°方向展布的渗漏沉积中心。锰矿产于南华系下统大塘坡组第一段(含锰岩系)下部黑色碳质页岩中，呈层状、似层状缓倾斜顺层产出，矿体长大于6 000 m、宽大于2 000 m，盆地中心部位矿体中夹一层含碳玻屑晶屑凝灰岩透镜体。该矿床是近年来运用古天然气渗漏沉积型锰矿床成矿模式与找矿模型理论发现的又一个隐伏超大型锰矿床，锰矿石资源量(332+333)1.92亿吨，位居亚洲第一、世界第五位。 |
| 英文摘要: |
| The Pujue super-large manganese deposit in Songtao，Guizhou province is controlled by pujue level Ⅳ depression basin. Because the synsedimentary faulting，the thickness of Liangjiehe formation，manganese orebody，the second section of Datangpo formation and Nantuo formation increase from south to north，basin have two show NE65° direction distribution of center of seep sedimentary.Manganese ore developed in the black carbonaceous shale in the lower part of the first section of Datangpo formation(manganese-bearing rock series)，lower series of Nanhua system.Ore bodies are bedded and stratoid.The ore body is over 6 km in length and 2 km in width.In the central part of the basin，there is a layer of carbon glassy - crystal - clastic tuff lens embedded in the ore bod.This deposit is another hidden supergiant manganese ore deposits discovered in recent years by using the mineralization model and prospecting model theory of ancient natural gas seepage sedimentary-type manganese ore deposit，the amount of manganese mineral resources(332+333)1.92 million tons ranks first in Asia and fifth in the world. |
