摘要
通过对该矿区含矿地层特征、矿石物质组分、有关元素含量的综合分析,以及中三叠世该区岩相古地理的研究,说明在中三叠世法郎期,随着海平面的快速上升,来自越北古陆和上地幔的含锰热液中的锰质,在海平面进入相对静止状态时,在半封闭的五凤海湾而聚集成矿。
Based on the comprehensive analysis on the character of the ore bearing strata, ore matter component, related elements in the mine and the research on Middle Cretaceous lithofacies and ancient geography in the area, It is illustrated that during Falang period of Middle Cretaceous epoch, with the rapid rising of the sea level, the manganese matter contained in manganese bearing hydrothermal fluid from North Vietnam old land and upper mantle accumulated to form the deposit on the half closed Wufeng bay when the sea level became relatively static.
