In this paper, in order to further research the physical properties, chemical structure and the actual causes significance of pyrite, we measured respectively the different middle pyrite samples from Hongtoushan with thermal imager. We obtained related thermoelectricity parameters, combined with pyrite metallogenic positions and its features to analyze it. Results show that: It was n-type for the conduction type of Hongtoushan pyrite, and there existed isomorphism substitution of the different degree in the lattice of the pyrite. This substitution was Co3+ and Ni4+ replaced Fe2+, it was the correlations between the type of isomorphism and the position of pyrite. Thermoelectricity had difference in depth.%为了深入研究黄铁矿的物理性质、化学结构的差异及其成因,以红透山矿区不同中段黄铁矿为样品,运用热电仪测量得出热电性相关参数,并结合黄铁矿成矿部位及其特征进行分析.结果表明:红透山黄铁矿(FeS2)呈电子心导电,导电类型为n型;晶格内部存在着Co,Ni对Fe的类质同象取代,该取代为异价Co3+,Ni4+取代Fe2+,类质同象取代的多少与黄铁矿形成的深度具有相关性,该区黄铁矿热电性存在深度差异.
