| 摘 要： | 本文用X射线粉末衍射法研究蒙脱石矿物的结晶度与其埋藏深度之间的关系,并作出地质解释。 在X射线粉末衍射图上,V/P值的大小即C轴的有序程度是蒙脱石结晶度的标志。V/P值与其生成时的深度有相关性,其相关曲线呈一似抛物线形。似抛物线的顶点位于不同的生成深度,这主要是各地区地热增温率及成矿温度不同所引起。

| Abstract: | The relationship between crystallinity and buried depth of montmori-llonite has been studied by X-ray powder diffraction, and its geological explanation has been made.
On X-ray powder diffraction pattern, the value of V/P ratio, i.e,C-axis' ordering degree is a mark of montmorillonite crystallinity.The value of V/P ratio is related to the buried depth of montmorillonite. The relative curve is a parabole-like diagram. The tops of the parabolelie in different forming depth mainly due to the different geothermic degree and mineral-forming temperature in different areas. |
