| 摘 要： | 利用电子探针检测安徽凤阳石英岩中的含铁矿物,测量由相同矿区的石英岩加工而成的不同粒度石英砂的Fe2O3质量分数(w(Fe2O3))与磁化率。结果表明:石英岩中有磁铁矿、黄铁矿、黑云母与白云母等多种含铁矿物。这些含铁矿物主要充填在石英颗粒孔隙中,粒度大多小于0.1 mm。而石英砂中的w(Fe2O3)普遍很低(小于0.1%),其磁化率主要受磁铁矿控制。并且不同粒度的石英砂中w(Fe2O3)与磁化率存在较大差异,当石英砂中的w(Fe2O3)大于0.01%时,由Fe2+、Fe3+磁性离子含量决定磁化率大小,两者存在强正相关关系。这也反映出了石英岩的铁含量与磁化率之间的关系。因此,磁化率可作为石英岩铁含量的替代性指标。

| Abstract: | Electronic probe is used to detect iron-containing minerals in quartzite from Fengyang County,Anhui Province.The content of Fe2O3 and magnetic susceptibility of different grain-size quartz sands separated from quartzite of the same mine area are measured.The results indicate that the quartzite contains several kinds of iron-containing minerals such as magnetite,pyrite,biotite and muscovite.These iron minerals are mainly fillings in the pores of quartz grains,the size of which is usually less than 0.1 mm.The... |
