| 摘 要： | 通过对马坑铁矿矿区控矿构造的剖析及开采过程对矿床成因的新认识，认为马坑铁矿为典型的矽卡岩构造控矿矿床。矿床发育着一套海进式的沉积建造地层，该套地层受后期热液蚀变改造从而形成此矿床。矿床层控构造的标志较为明显，并且受区内褶皱、断裂构造的控制。矿床在海西早期的构造动力条件与整个闽西南区域性的主体构造动力条件不同，并且经历过明显的同沉积构造变动。

| Abstract: | In light of the analysis of ore-control structure in the mining area and new understanding to the ore genesis,it is concluded that Makeng iron mine is a typical skarn structure ore-control deposit.A transgression sedimentary strata comes into the deposit through the transformation of hydro-thermal alternation.The ore-control structure in Makeng owns an obvious symbol and is controlled by folds and faults.The tectonic dynamic condition of Makeng,which is different from the regional tectonic dynamic condition... |
