| 摘 要： | 在电子探针微区化学成分分析的基础上,结合 X 射线粉末衍射分析,对福建紫金山铜金矿床中的 Cu-S 体系矿物进行 了化学成分和晶体结构特征的研究。结果在该矿床中发现较完整的 Cu-S 体系矿物系列,包括铜蓝、雅硫铜矿、斯硫铜矿、 吉硫铜矿、斜方蓝辉铜矿、蓝辉铜矿、久辉铜矿和辉铜矿。此外,利用粉末 X 射线衍射数据,计算了铜蓝、斜方蓝辉铜矿、 蓝辉铜矿、久辉铜矿、辉铜矿等五种矿物的晶胞参数。基于系统矿物学的研究,建立了紫金山铜金矿床 Cu-S 体系完整矿物 的结晶与变化序列,该工作在国内尚属首次,同时也丰富了 Cu-S 体系矿物基础矿物学研究的资料。

| Abstract: | This paper presents a new study of the complete Cu-S minerals from the Zijinshan Cu-Au deposit, based on electron- microprobe and X-ray diffraction analyses. All copper sulfide minerals present in the Cu-S series were identified here, including covellite, yarrowite, spionkopite, geerite, anilite, digenite, djurleite, and chalcocite. The cell parameters of covellite, anilite, digenite, djurleite, and chalcocite were calculated using the X-ray diffraction data. The sequence of crystallization and phase variations of the Cu-S minerals exposed in this deposit are established according to their systemic mineralogical study for the first time in China. This study also contributes to enrich the materials of mineralogical study of Cu-S series minerals. |
