Based on the analysis of the geological background, regional geological conditions of mineralization, ore-forming mechanism, by applying theories and methods of minerageny and prospecting mineralogy, using the modern testing technology, the typomorphic characteristics of arsenpyrite in the Bake gold deposit were studied in this paper, achieving important information on the genesis of ore deposits from the view of another point. The results show that gold-bearing arsenopyrite in ore bodies have the features of small size, poor crystallinity, unit cell parameters close to the theoretical value, N-type thermoelectricity, and the mean value of -195.6 μV/℃ for pyroelectric coefficient which is significantly lower than that of arsenopyrites adjacent to the surrounding rocks (-185.1μV/℃) and that far away from the surrounding rocks (-174.6μV/℃).
