利用透射电子显微技术测定了湖北大冶铁山矿床中的微米级葡萄石空间群。选区电子衍射几何构图法分析表明，该矿物系斜方晶系，衍射消光符号为Pn，晶胞参数为a＝0．458，b＝0．555和c＝1．853nm。[100]和[301]方向的会聚束电子衍射花样研究表明，其空间群为Pncm。
Transmission electron microscopy was used to determine the microscopic gravel cluster space in the Daye-Tieshan deposit, Hubei Province. The analysis of the selected area electron diffraction geometry shows that the mineral is orthorhombic, the diffraction extinction symbol is Pn, the unit cell parameters are a = 0.458, b = 0.555 and c = 1.853nm. Convergence electron beam diffraction pattern studies in [100] and [301] directions show that the space group is Pncm.
