摘要
This paper studies the chemical and mineralogical compositions of red clays in Wuming and Guilin by means of chemical analysis, X-ray diffraction test, Bogue method and K-value method. The results show that Kaolinite, gibbsite, goethite are found in both clays and quartz is additionally found in Guilin red clay. The contents of Kaolinite, gibbsite, goethite (<2 mm) and goethite (>2 mm) are respectively equal to 74.0%,12.53%,2.22% and 8.37% in Wuming red clay. The contents of Kaolinite, gibbsite, goethite and quartz are respectively 56.59%,11.44%, 15.61% and 12.45% in Guilin red clay.
