本文在野外观察和室内岩矿工作的基础上,对云南曼养铁矿进行了成矿实验研究.结果表明,模拟实验体系钙铁辉石一钠长石一方铁矿十三氯化二硼(Hd-Ab-W(?)+B_2O_3)在1125℃存在一个较大的液相不混溶厂.对铁矿的原始岩浆、铁矿及富硅相的熔体自由能计算也证明了曼养铁矿原始熔状分相的可能性.本文的实验研究支持了曼养铁矿的矿浆成矿假说.
Based on the field observation and indoor rock-mine work, this paper carried out the metallogenic experiment on Manyang iron ore in Yunnan Province.The results show that the calcareous pyroxene-monosodium-feldspar- Hd-Ab-W (?) + B_2O_3) has a large liquid-immiscible plant at 1125 ° C. The melt free energy of the original magma, iron ore and silicon-rich phase of iron ore also proves that man-made Possibility of original melting phase of iron ore.The experimental study in this paper supports the ore-forming hypothesis of Manyang iron ore.
