现代海洋沉积物X射线衍射全矿物分析方法

Modern X-ray Diffraction Whole-mineral Analysis Method for Marine Sediments

现代海洋沉积物中成分非常复杂,同时存在几种、十几种不同类型的矿物,将其进行全矿物分析在海洋地质学中有着重要的意义。X射线衍射(XRD)全矿物分析已成为海洋地质研究的通用方法。虽然XRD分析方法不断成熟和完善,但是一直没有一个统一的、放之四海而皆准的方法。该文介绍一种相对简单、快捷的XRD全矿物分析法,暂且称作强度因子法。普遍适用于现代海洋沉积物的物相定量分析方法,为现代海洋地质研究提供可靠的地质数据。

The composition of modern marine sediments is rather complex,and there are several,even more than ten,different types of minerals in existence.A whole mineral analysis of these minerals is of great significance in marine geology.X-ray diffraction(XRD)whole mineral analysis has become a general method for marine geological research.Although the XRD analysis method is becoming increasingly mature and perfect,there has not been a unified and universal method.This paper introduces a relatively simple and rapid XRD method for whole mineral analysis,which is temporarily called Intensity Factor Method.The phase quantitative analysis method,which is generally suitable for modern marine sediments,provides reliable geological data for geological research on modern marine.
