胶东地区探明金储量超过5000t,是我国最重要的金矿集区。玲珑金矿区位于胶东西北部招-平断裂北段,具有典型含金石英脉矿床的特征。矿区部分矿段产出富碲铋化物的明金矿石,是研究富碲铋化物金矿床成因和金超级富集机制的理想对象。通过显微岩相学观察、扫描电镜及电子探针分析,首次对胶东玲珑金矿区富碲铋化物明金矿石的矿物组合和形成机制进行了较为详细的研究。玲珑金矿区含明金矿石中的金矿物主要为含银自然金,成色整体较高,平均为894。共发现了五种与自然金共生的碲化物,分别是辉碲铋矿、碲铋矿、碲银矿、碲铋银矿和碲镍矿,其中辉碲铋矿含量最多。通过矿物共生组合研究及物理化学条件分析,确定成矿流体的碲逸度范围为-12.6 < logf<sub>Te<sub>2</sub></sub> <-9.1,硫逸度范围为-13.6 < logf<sub>S<sub>2</sub></sub> <-9.6。碲、铋元素的富集指示了深成幔源的信息,碲、铋等物质可能来源于古太平洋板块俯冲。玲珑金矿区大颗粒自然金的超级富集与碲、铋等元素密切相关,且银碲化物的产出提高了自然金的成色。;Jiaodong gold province has proved gold reserves of more than 5000t, which is the most important gold concentration area in China. Linglong gold district is located in the northern section of Zhao-Ping fault in the northwest of Jiaodong Peninsula, and it has the typical characteristics of a gold-bearing quartz vein deposit. Some of the ore sections in this mining area produce tellurium-bismuth enriched gold ore, therefore, it is an ideal object to study the relationship of the genesis of ore deposits and the extreme enrichment mechanism of gold with the enriched tellurium-bismuth. Through microscopic observation, scanning electron microscope analysis (SEM) and electron probe micro-analysis (EPMA), the mineral assemblages and formation mechanism of tellurium-bismuth enriched gold ore in Linglong gold district were studied in detail for the first time. The gold minerals in Linglong mining area are mainly silver-bearing native gold, and the gold fineness is high with an average of 894. Five kinds of tellurides co-occurring with native gold have been found, namely, tetradymite, tellurobismuthite, hessite, volynskite and melonite, among which the tetradymite is the most abundant. According to the study of mineral assemblages and analysis of physical and chemical conditions, the range of tellurium fugacity in the ore-forming fluid is determined to be -12.6 < logf<sub>Te<sub>2</sub></sub> < -9.1, while the sulfur fugacity range of -13.6 < logf<sub>S<sub>2</sub></sub> < -9.6. The enrichment of tellurium and bismuth indicates they are formed by a deep mantle source, and to be more specifically, the tellurium and bismuth may have been derived from the subduction of the paleo-Pacific plate. The rich concentration of large grains of native gold in Linglong gold district is closely related to tellurium and bismuth, and the precipitation of silver telluride improves the fineness of native gold.
