摘要
In order to study the chemical composition and the metallogenic characteristic of Hongtoushan pyrite,we measured the infra-red transmittance spectra of different pyrite samples taken from the middle part of the Hongtoushan,within the range of 400-4000 cm-1,by using the Fourier Transform Infra-red Spectrometer of NICOLET 380 type with the resolution>0.9 cm-1.Based on the Lambert-Beer Law,the absorbance of different pyrite samples was calculated.The results show that there exist different isomorphism substitutions in Hongtoushan pyrite(FeS2),and that the conduction type of this regional pyrite is the n-type.It is thought that there exist the correlation between the isomorphism and the location of the pyrite.We also found the ratio of the absorbance is negatively correlated to the depth of pyrite location.
