摘要
介绍了广西大新锰矿矿床的基本地质特征及其成因。热液沉积锰矿层产于浅海深水台沟沉积相中,矿物的同位素组成表明矿物质主要来自海底深部岩浆热液,陆源次之,矿体赋存上泥盘统五指山组地层中,矿体受海底热液作用控制,为沉积热液锰矿床。
It introduces the basic geological characteristics and causes of manganese ore in the deposit of Daxin of Guangxi. The manganese ore layer of hydrothermal sedimentary originates from deposition phase of deepwater groove platform in neritic region. The isotopic composition of the minerals shows that the minerals are mainly from the magmatic hydrotherm in deep, and terrigenous sediments come second. The ore body which exists in the layer of Five Finger Mountains belong to the Mud Plate Series, as is sedimentary hydrothermal manganese ore bed. It is controlled by submarine hydrothermal solution.
