| 摘 要： | 本文通过电子探针微束分析,在胶东牟平-乳山成矿带内的英格庄金矿发现碲银矿、辉碲铋矿,并在胶东地区首次发现楚碲铋矿,该矿物系列以复杂的连生关系呈细小片状产出于白云石及石英矿物颗粒间。碲化物电子探针化学成分结果显示本区碲化物普遍贫碲。依据碲化物及其共生矿物的产出关系和矿物化学成分,推测其形成顺序为黄铁矿→镍黄铁矿→辉碲铋矿→楚碲铋矿→碲银矿。依据碲化物矿物共生组合对体系中碲化物形成时的fTe2和fS2进行了限定,log fTe2范围为-19.5~-11.2,log fS2上限为-16.8;并试图对碲的来源及其地质意义进行探讨,认为英格庄金矿中碲化物的发现揭示了深成幔源的信息,鉴于碲与金相近的地球化学特征和密切关系,认为金矿赋矿围岩荆山群和昆嵛山杂岩体提供成矿物质来源的可能性不大,而早白垩世的构造-岩浆活动特别是壳幔物质的交换过程与金成矿关系更为密切。 |

| Abstract: | Based on electron probe micro-analysis (EPMA),hessite and tetradymite are found in the Yinggezhuang gold deposit,and tsumoite found the first time in Jiaodong district also occurs in the Yinggezhuang gold deposit,one part of the Mouping-Rushan ore belt,Jiaodong.These telluride minerals intergrowing with each other in fine flakes occur in the inter-crystal poroses of dolomite and quartz.The lower contents of tellurium in the telluride minerals studied are revealed by the results of EPMA.The precipitation seq... |
