| 摘 要： | 为了深入研究黄铁矿物理性质的实际成因意义，利用NICOLET 380型，分辨率＞0.9 cm-1傅立叶变换红外光谱仪，对红透山地区不同中段的黄铁矿样品进行测量，在400~4 000 cm-1范围内分别得出红外光透射光谱图。运用朗伯比尔定律计算出各中段样品的吸光度。结果表明：红透山黄铁矿(FeS2)中存在不同程度的类质同象取代，该区域黄铁矿导电类型为n型。认为此种类质同象与黄铁矿形成部位具有相关性。吸光度比值与样品所在深度负相关。

| Abstract: | 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. |
