摘　　要：采用定向晶片法对陕西潼关—河南灵宝蛭石进行了X射线研究,结果表明河南灵宝石板沟和陕西潼关李家乡蛭石矿"蛭石"的矿物组成主要为金云母 蛭石的规则或不规则间层矿物;程村藏马峪"蛭石"的矿物组成主要为罕见的大片状绿泥石 蛭石的间层矿物。对比样品的定向晶片法与粉末法的X射线衍射谱可以发现,定向晶片法更能揭示晶片中不同晶层的间层结构特点,特别是对于分结型间层矿物,可以从衍射谱图上直接确定分结型间层的组元。X-ray diffraction of oriental single crystal slices is used to study the interstratification structure of vermiculite in ores from Tongguan, Shaanxi and Lingbao, Henan. It is revealed that vermiculite from Shibangou, Lingbao and Lijiaxiang, Shaanxi consists of phlogopite-a vermiculite interstratified mineral, and vermiculite from Chuangmayu, Lingbao, consists of chlorite-a vermiculite interstratified mineral. This research also shows that X-ray diffraction analysis of oriental single crystal slices is a powerful method to study macro parcel interstratification minerals, especially segregated interstratification minerals.
