中文摘要：

采用Fourier变换红外吸收光谱和X射线粉晶衍射技术对四川石棉县蛇纹石猫眼进行了研究。红外吸收光谱结果表明：四川蛇纹石猫眼可分为纤蛇纹石和叶蛇纹石两种类型，两者在（960—1100）cm^-1和（3600—3690）cm^-1的范围内由Si-O伸缩振动的E1类振动和OH伸缩振动表现出的红外谱带分裂强度及谱带特征存在明显的差异。在（960—1100）cm^-1间：纤蛇蚊石的红外光谱分裂成三个明显的谱带，而叶蛇纹石在此区间只有两条谱带。在570cm^-1附近的红外谱带以肩状出现；OH伸缩振动区：纤蛇蚊石出现两条红外谱带，而叶蛇蚊石只出现一条红外谱带。X射线粉晶衍射结果表明：叶蛇蚊石具有d202=0．2522nm（I／I0=19）和d203=0．2430nm（I／I0=18）的特征谱线，而纤蛇纹石则具有d202、006=0．2446nm（I／I0=29）的特征谱线，d020〉0．245nm近0．249nm的特征谱线缺失。

英文摘要：

FTIR absorption spectra and XRD were used to study serpentine cat＇s eye from Sichuan province in this paper. The results indicate that serpentine cat＇s eyes includes two types： chrysotile and antigorite, which have the characteristic bands in the Si - O Stretching vibration region around （960 - 1100 ） cm^-1 and OH Stretching vibration region around （ 3600 - 3690 ） cm^-1 respectively. Around （ 960 - 1100 ） cm^-1, chrysotile displays three bands of absorption, while antigorite only has two bands. Upon 570cm^-1, antigorite shows a shoulder absorption band. XRD shows that antigorite is characterized by the lines d202 =0. 2522nm （I/I0= 19） and d2o3 =0. 2430nm （I/I0 = 18 ） ,while chrysotile only has the line d202,006 = 0. 2446nm .（ I/I0 =29） without the line near d020 =0. 250nm.
