///The Jiamante gold deposit in Nilka County of Xinjiang is hosted in a suite of intermediate-acidic lavas and pyrodastic rocks of the Lower Carboniferous Dahalajunshan Formation, and is controlled by a volcanic edifice, with ore bodies being in vein-like and lenticular forms. The ore minerals include chalcopyrite, galena, sphalerite, pyrite, limonite, stibnite, covellite, native gold and native silver, whereas the gangue minerals consist mainly of quartz, calcite, sericite and kaolinite.  The results show that ore-forming fluids are characterized by low temperature, low salinity and low density. Thus, the characteristics of ore-forming fluid system and ore geology of the Jiamante gold deposit suggest that the ore deposit is of the mesothermal to epithermal lode type, representing a transition from porphyry to epithermal mineralization.
