摘　　要：通过电子探针、镜下显微、X射线衍射和红外吸收光谱等方法,对南天山红柱石矿物的化学成分、微形貌特征和显微结构、晶体结构等进行了系统研究。分析表明南天山红柱石富含Al,含微量Fe、Mg、Na、Cr、Ti、Mn和Ca;红柱石为斑状变晶结构,片状构造;晶胞参数为a0=0.782nm,b0=0.786nm,c0=0.555nm;红外吸收光谱特征与理想图谱基本一致。Chemical composition, microscopic characteristics, microscopic structure and crystal structure of andalusite from South Tianshan Mountains were systematically analyzed by such means as electron microprobe analysis, microscope observation, X-ray diffraction and infrared absorption spectra. The results show that the andalusite there has rich Al and contains small amounts of Fe, Mg, Na, Cr, Ti, Mn and Ca, that this mineral assumes porphyroblastic texture and sheet structure, that the unit cell parameters are ao O. 782 nm, b00. 786 nm, and co O. 555 nm respectively, and that the charac- teristics of its infrared absorption spectra are in accordance with those of the ideal atlas.
