摘要
采用扫描电镜与波谱学技术（ＥＰＲ谱和激光拉曼谱）相互配合的方法，获得了小秦岭地区的含金黄铁矿中存在有晶格金的佐证．在扫描电镜下，黄铁矿中Ａｕ的ｘ射线面分布图呈均匀分散的细小斑点；Ａｕ＋的ＥＰＲ超精细结构谱线ｇ因子为２．０５±０．１５；Ａｎ＋－伸缩振动的拉曼位移，经计算和实验测定Δｖ为３７０～３９０ｃｍ－１．
So far,lattice gold has been discovered continuously in pyrite in many gold deposits,but it has never beenfound in the Xiao Qinling auriferous mineral zone. Thus. the author studies the gold-bearing pyrite whichwas generated in the Xiao Qinling auriferous mineral zone by using scanning electron microscope and wavelength dispersive spectromater and gets the evidence for lattice gold in gold-bearing pyrite. The X-ray surfacedistribuing graph shows the An beared in pyrite is even and disperse small speckes. By using the EPR spectrum analysis, a fine texture spectral line with g(factor) =2. 05±0. 15 wes obtained. Raman line shift (Δγ) of flexible vibration of An+ - is 370～390cm-1. that is experimened and calculated by the author.
