| Abstract: | 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. |
