摘要
本文通过成矿地球化学的研究,认为龙桥铁矿床为火山一次火山热液成因,并列举如下成矿地球化学证据:(1)成矿物质主要来自于岩浆;(2)磁铁矿的形成与热液作用有关;(3)成矿作用具明显的阶段性。最后论述了矿床的形成条件和定位机制。
The Longqiao iron ore deposit is thought to be of volcanic-subvolcanic hydrothermal gen- esis through metal logeochemical study, which is supported by the facts as follows: (1)ore-forming mate- rial is substantially derived from magma, (2) the formation of magnetite is related to hydrothermal pro- cess; (3) the metallogenetic process shows marked stages. Finally, the formation condition and emplace- ment mechanism are concluded for the deposit.
