摘要
应用Ｘ射线衍射定量分析方法中的基体清洗法及其演化而来的自清洗法对粘土中常见矿物蒙脱石、绿泥石、高岭石、伊利石、长石、方解石、白云石、赤铁矿、蛋白石的Ｋ值进行了实验测定。在此基础上提出了采用稀释法，即外加一定量石英对由于粘土矿物结晶度和定向度差异所引起定量分析偏差进行修正的方法。
K values of common minerals including montmorillonite, chlorite, illite, kaolinite, feldspar, calcite, dolomite, hematite and opal were determined by using matrix flushing and auto flushing methods which were adopted from X ray diffraction quantitative analysis methods . Based on these testing methods, the authors adopted the dilute method to revise the quantitative deviation which resulted from the difference of crystallinity and directionality of clay minerals.
