Our investigation shows that neither the dioritic porphyry nor the sedimentary rock is the source of iron ores, and that the source of most ironrich orebodies is the ore magmahydrothermal system in the deep chamber. Ore magma which was formed by liquid immiscibility is the main source of Gushan deposit, and the residual ironrich hydrothermal fluids which occurred as NaFeCl complex is the main source of Baixiangshan deposit.
根据野外观察和地球化学研究,文中认为,闪长玢岩岩体和沉积围岩均不是铁质的主要来源,富铁矿体的成因主要来自矿田深部的矿浆热液系统,姑山式铁矿的铁质主要是液态不混溶作用形成的铁矿浆,白象山式铁矿的铁质主要来源于深部残浆分离出的NaFeCl络合物。
