弓长岭铁矿是我国典型的沉积-变质型铁矿,对本矿区富铁矿和标型矿物的研究一直都是矿床研究的重点,而对标型矿物之一的石榴石的研究有着非常重要的意义。石榴石广泛分布于含铁矿层特别是富铁矿层的顶底板及周围的围岩中,当铁铝石榴分子含量较高时,在一定程度上可以作为含铁矿层特别是富铁矿层赋存的一个标识。
The Gongchangling iron ore is a typical sedimentary-metamorphic iron ore in our country. The research on iron-rich ore and standard minerals in this area has always been the focus of the deposit research. However, it is very important to study the garnet, one of the standard minerals Meaning. Garnets are widely distributed in the top and bottom of iron-bearing ore bed, especially iron-rich ore bed and the surrounding rock. When the content of iron-aluminum pomegranate is high, it can be used as a part of iron-bearing ore bed, especially iron-rich ore Layer identification of a deposit.
