磁铁矿是最常见的金属矿物之一,以往研究的也比较详细。其内部结构一般有环带结构,双晶结构和固溶体分解结构,分别由不同的形成环境所决定。我们在研究安徽霍邱,辽宁鞍山等地磁铁石英岩型铁矿床的磁铁矿时,发现它们还具有一种“鳞片结构”,形状特殊,分布普遍,尚未见报导。 Magnetite is one of the most common metal minerals, the previous study is also more detailed. Its internal structure generally ring structure, twin structure and solid solution decomposition structure, respectively, by the formation of different environments. When we studied the magnetite of the magnetite quartzite type iron deposits in Huoqiu, Anhui and Anshan of Liaoning, we found that they also have a “scale structure” and have not yet been reported because of their special shape and distribution.
