摘要
桃江响涛源锰矿产于局限贫地的边缘,在时间、空间及成因上与黑色页岩有密切的关系。基于对含矿岩系地球化学剖面与地球化学特征的研究,确定了在含矿沉积序列中存在两次缺氧事件,成矿作用受氧化—还原条件的控制。成矿物质主要来源于盆地内黑色页岩中锰的活化与转移,矿床具有水成—碎屑成岩成因的特点。
Located on the margin of the confined basin. Taojiang manganese deposit is temporally and spatially as well as genetically related intimately to its adjoining rock-black shale. Two stages of anoxia events have been identified through studies on geochemical profile and geochemicad characteristics of the ore-bearing sedimentary sequence. The deposit is characterized by hydrogenic-diagenetic origin with mineralization controlled by redox conditions. Metallogenic material mainly derived from the remobilization and transportation of manganese in the black shale of the basin.
