火成岩的磁性矿物,特别是磁铁矿的物理,化学特征的高度指示性,可作为确定矿体的找矿评价标志。在这方面,年青火山岩中钛磁铁矿研究的结果是饶有兴味的。但是对侵入的花岗岩类岩石进行研究,由于这些岩石中的磁性矿物部分是原生钛-铁氧化矿物复杂变化后的产物,故工作中的复杂性就要大得多。 本文是对蒙古人民共和国东部大量稀有金属花岗岩类岩体的磁铁矿副矿物研究结果的总结。
The igneous magnetic minerals, especially the highly indicative of the physical and chemical features of magnetite, can be used as a sign of ore prospecting for ore body determination. In this regard, the results of the study of titanium magnetite in young volcanic rocks are very interesting. However, the study of intrusive granitic rocks shows that the complexity of the work is much greater since the magnetic minerals in these rocks are the result of complex changes in primary titanium-iron oxide minerals. This article summarizes the results of magnetite mineral studies on a large number of rare metal granitoids in the eastern part of the People’s Republic of Mongolia.
