摘要
内蒙古白乃庙金矿自然金的晶体形态,大多数是立方体{100}、菱形十二面体{110}和八面体{111}的聚形。另外,还发现一些立方体{100}和八面体{111}的聚形晶体等。自然金的晶体形态与其成分有关。杂质越少,晶形越简单。该矿床大部分已被剥蚀,深部矿化作用逐渐减弱。通过研究,笔者认为白乃庙金矿属中—深成类型。
The crystal morphology of native gold occurring in Bainaimiao gold deposit, Inner Mongolia, shows a lot of polyhedrons of combination of the cube {100}, dodecahedron -{110} and octahedron -{111}. In addition, some of the combinations of the cube {100} and octahedron {111} etc.,have been found. On the other hand, the crystal morphology of native gold is related to its composition; the simpler composition, the less impurities. Bainaimiao gold deposit was formed inter-mec-liate-deepseated. Many mineral bodies have been eroded. The mineralization of gold would be gradually reduced downward in the deposit.
