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, f_Te2, f_S2, f_O2 and pH value. Pyrite-quartz stage and quartz-pyrite stage formed under the conditions log f_Te2 < -14.4, and log f_S2=-11.1~-6.5. Gold-tellurides stage formed under the conditions t=110~313℃, log f_Te2=-15.2~-9.4, and log f_S2=-16.5~-14.6, with increasing f_O2 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.
