中文摘要: |
本文通过对松桃—印江地区大塘坡组一段“含锰岩系”的岩石组合特征分析,阐述了含锰岩系“三个微相”的划分方案,认为杨立掌、大塘坡、大屋、黑水溪等锰矿聚集区属盆地中心微相,其周围附近属盆地外围微相,距盆地较远地带属水下隆起带微相。依据盆地中心与水下隆起带的位置关系、盆地中心之间的间距、控矿构造等分析,认为乌罗司—望秀—石门坎一带极有可能存在一个较大的聚锰盆地。 |
英文摘要: |
By the feature analyses of manganese-bearing rock components of Datangpo formation in Songtao-Yinjiang area, the division plan of 3 manganese-bearing rock micro-facies is introduced, it’ thought Yanglizhang, Datangpo, Dawu and Heishuixi manganese accumulation areas are central basin micro-facies, the others are outside basin micro-facies, the area far away from basin is uplift under river micro-facies. According to the relation between basin center and underwater uplift zone, the distance of basin centers and ore-controlling factors, it’s thought there may be a big manganese accumulation basin in Wuluosi-Wangxiu-Shimenkan area. |
