中文摘要：

松里沟金矿位于华北陆块南缘熊耳山地区，已探明金资源储量26 t。矿体产于中新太古界-古元古界太华群片麻岩NWW向的断裂带中。其热液成矿过程包括4个成矿阶段：黄铁矿-石英阶段、石英-黄铁矿阶段、金-碲化物阶段和石英-碳酸盐阶段。显微镜下发现金-碲化物阶段存在大量与金共生的碲化物。利用电子探针和能谱分析查明碲化物的种类、共生关系和形成条件，确认的碲化物有碲铅铋矿、碲铅矿、碲铋矿、碲金矿、碲金银矿、硫碲铋铅金矿、辉碲铋矿，此外还有大量的自然金和少量的辉铋矿。该矿床为一与岩浆作用有关的碲金矿床。Au主要以自然金和金银碲化物的形式存在。Au、Ag以硫氢络合物的形式发生迁移，Te2（g）和H2Te（g）冷凝进入含贵金属的氯化物溶液是碲化物沉淀主要机制。相图及化学反应方程式分析表明，金-碲化物阶段受温度、碲逸度、硫逸度、氧逸度和酸碱度控制，其中，黄铁矿-石英阶段和石英-黄铁矿阶段形成于logfTe2 〈 -14.4和logfS2=-11.1~-6.5的环境。金-碲化物阶段形成于温度为110~313℃、logfTe2=-15.2~-9.4和logfS2=-16.5~-14.6、fO2升高和pH值降低的环境。碲化物的发现为探讨该矿床成因和熊耳山地区寻找同类型的矿床提供了依据。

英文摘要：

The Songligou gold deposit（26 t Au） which is confined in NWW-trending fracture of Meso-Neoarchean to Paleoproterozoic Taihua Group gneiss is located in the Xiong＇er Mountain area, forming a part of the southern margin of the North China Craton. The ore-forming hydrothermal processes can be divided into four stages： pyrite-quartz stage, quartz-pyrite stage, gold-tellurides stage, and quartz-carbonate stage. Microscopic observation reveals that large amounts of tellurides display affinity with gold. In order to clarify mineralogy, intergrowth relationships and ore-forming conditions, the authors conducted electron microprobe and energy spectrum analyses. The results show that there are many subtypes of tellurides such as rucklidgeite, altaite, tellurobismuthite, calaverite, petzite, buckhornite and tetradymite. Additionally, abundant native gold and a littlle bismuthinite were also detected. The Songligou gold deposit is a Te-Au gold deposit related to magmatism. Gold mainly exists in the forms of native gold and Au-Ag-telluride. Au and Ag were transported by the bisulfide complexing. Condensation of Te2（g） and H2Te（g） into chloride solution containing noble metals seems to have been the main mechanism for telluride precipitation. Furthermore, phase diagrams and chemical reaction equations suggest that gold and tellurides formation was mainly controlled by the t, fTe2, fS2, fO2 and pH value. Pyrite-quartz stage and quartz-pyrite stage formed under the conditions log fTe2 〈 -14.4, and log fS2=-11.1~-6.5. Gold-tellurides stage formed under the conditions t=110~313℃, log fTe2=-15.2~-9.4, and log fS2=-16.5~-14.6, with increasing fO2 and reducing pH value. Overall, the discovery of telluride in the Songligou gold deposit provides an ideal basis for deciphering the genesis of this deposit, and also offers useful information for exploration of the similar gold deposits in this area.
