Liaoning fushun "Hongtoushan type" copper-zinc mineral is come from the areas of the archean granit,greenstone terrain in Qingyuan of Liaoning province. Hongtoushan deposit is the oldest known l(?)mp sulfide copper-zinc deposit in China. As one of the main ore minerals in Hongtoushan Cooper-Zinc deposit, it occupies 40-90% of the main sulphide component content, it is the in,portant symbol mineral for ore-prospecting work.In this paper,(?)e measure respectively the different middle pyrite samples in Hongtoushan, and use the pyroelee ricity and infrared spectrum to research the pyrite in Hongtoushan. We try to further research the physical properties, physical parameter, chemical structure and the actual causes significance of (?)e pyrite.Using a thermal in iger, we measure the thermoelectricity related parameters of the pyrite samples in -467 and -(?)47 section. Combined with the pyrite metallogenic parts and its characteristics to analyst And comparatively analyze the thermoelectricity parameters of JinQingding pyrite and sy thetic pyrite samples, conducting type. With the FTIS (Fourier Transform Infrared Spectron eter) of NICOLET 380 type, resolution>0.9 cm*-1,we measure respectively the pyrite sample of Hongtoushan in-467,-507,-587,-647,-707,-767 six different sections, obtained infrared tra(?)mittance spectra within 400-4000 cm-1 range. According to infrared spectrum data calculat(?)n infrared spectrum parameters, based on Lambert-Beer Law, we calculate the absorbance of th(?) different middle pyrite samples.Results show that:All the py ite's coefficient of thermal particles are negative, it is n-type which the conduction type of Hong oushan pyrite. The thermoelectricity has difference in depth in Hongtoushan pyrite. With the dee(?)ening of deposit parts, the thermoelectricity coefficient and compensation thermoelectric potentia are negative heighten, thermoelectric field from p-n-type into n-type, electronic conductivity (?)oncentration rises. The absorption bands stretch to the high-frequency spectrum in the direct on of displacement comparing to the standard infrared bands. It exists isomorphism substitutio, of the different degree in the lattice of the pyrite. This substitution is that Co3+ Ni4 replace (?) Fe+, it is the correlations between the type of isomorphism and the position of pyrite. We reach that the ratio of the absorbance is negative correlation with the pyrite sample in different depth.
