利用二级轻气炮将6mm直径的钢球加速到5～7km／s后撞击石英砂岩靶，利用磁性分选、扫描电镜和X射线衍射等方法对岩靶受击后形成的碎屑进行了矿物分类和鉴别。碎屑主要由石英、高硅玻璃、微量柯石英以及铁碎屑、微细钢球等组成。70％的碎屑分布在0．097～0．90mm范围内。无一弱磁性碎屑约占总重量的92％，其它为强磁性碎屑。
After the ball of 6mm diameter was accelerated to 5 ~ 7km / s with two light gas guns, the quartz sandstone target was impacted, and the debris formed by the rock target was subjected to magnetic separation, scanning electron microscopy and X-ray diffraction Mineral classification and identification. Debris is mainly composed of quartz, high silica glass, trace coesite and iron scrap, fine steel balls and other components. 70% of the debris distribution in the range of 0.097 ~ 0.90mm. None of the weak magnetic debris accounted for about 92% of the total weight, the other for the strong magnetic debris.
