为了研究吉林陨石的透明矿物,我们进行了显微镜观察,测量了矿物的光性数据;用X射线粉晶法及X射线粉晶衍射法鉴定矿物;用电子探针及单矿物化学分析测定矿物的化学成分。Ⅰ号陨石人工重砂大样(10公斤)的选矿工作,提供了丰富的副矿物样品,大大充实了吉林陨石透明矿物的研究内容。 通过工作,确定了吉林陨石26种透明矿物,其中主要透明矿物2种,次要透明矿物7种,副矿物及微量矿物17种(表1)。现将各矿物主要特征分述如下:
In order to study the transparent minerals of Jilin meteorite, we conducted microscopic observation, measured the photophysical data of minerals, identified the minerals by X-ray powder crystal method and X-ray powder diffraction method, and determined the content of minerals by electron probe and single mineral chemical analysis chemical composition. Ⅰ meteorite artificial heavy sand sample (10 kg) beneficiation work, providing a wealth of deputy mineral samples, greatly enriched the Jilin meteorite transparent mineral research. Through the work, we have identified 26 kinds of transparent minerals in Jilin meteorite, including 2 kinds of major transparent minerals, 7 kinds of minor transparent minerals, 17 kinds of minor minerals and trace minerals (Table 1). Now the main characteristics of each mineral are described as follows:
