| 摘 要： | 大别山区石英质玉属新近发现的一种石英质玉(简称"大别山玉"),具色彩绚丽、质地细腻温润等特点。利用偏光显微镜、扫描电子显微镜、X射线粉末衍射、化学分析、红外光谱分析等方法,重点对"大别山玉"的矿物组成、化学成分、物理光学性质、微结构、红外吸收光谱等特征进行研究。结果表明,"大别山玉"具较典型的微粒-细粒结构,主要矿物为石英,含少量的绢云母、绿泥石、萤石、黄铁矿及其它粘土矿物等次要矿物,实属石英质玉;其化学成分相对较纯,主成分为SiO2,含少量的Al2O3,CaO,MgO,Fe2O3,FeO,K2O等;其红外反射光谱以Si—O非对称伸缩振动致特征的1177,1104 cm-1谱带、Si—O—Si对称伸缩振动致800,781cm-1分裂谱带以及由Si—O弯曲振动致492 cm-1较强谱带和542 cm-1弱谱带为特征。同时,还对"大别山玉"的结晶度及水的赋存状态一并给予了探讨。
