The Qijia gold deposit is a recently discovered quartz-vein type gold deposit located in the Chifeng-Chaoyang gold district along the northern margin of the North China Craton, hosted in the Mesozoic porphyroid granite. The gold mineralization can be divided into three mineralization stages: quartz±pyrite, quartz-polymetallic sulfide, and quartz-carbonate±pyrite. The gold mineralization is closely related to the silicification and sericitization. Based on field geological investigations, we systematically studied the occurrence state of gold from the Qijia gold deposit by using optical microscope and scanning electron microscope observations, combined with electron microprobe analysis for gold grains. The results indicate that gold in the Qijia gold deposit primarily occurs in three forms: fissure gold, interstitial gold, and inclusion gold. Gold grains are mainly observed in pyrite, followed by quartz, with occasional occurrences of chalcopyrite and galena. According to the grain size, gold can be subdivided into coarse-grained gold, medium-grained gold, fine-grained gold, and micro-grained gold, with fine-to micro-grained gold dominant. Gold exhibits diverse morphologies, predominantly granular-based, along with needle-like, leaf-like, hook-like, and branch-like forms. The compositions of gold grains are primarily Au and Ag, with gold fineness range between 678 and 883. They are mainly native gold and electrum, containing trace amounts of Te, Fe, and S. Based on comprehensive geological and geochemical characteristics, we proposed that the Qijia gold deposit belongs to the mesothermal magmatic-hydrothermal type gold deposit.
