| Abstract: | Systematic studies have been made of clay minerals in the laterite developed from carbonate rocks in Guizhou by means of X-ray diffraction, infrared spectroscopy, differential thermal analysis, scanning electron microscopy and transition electron microscopy. The results show that kaolinite and 0. 7 nm-sized halloysite are the major clay minerals in the laterite developed from carbonate rocks, and secondary minerals include illite, vermiculite, chlorite, chlorite/vermiculite interstratified minerals, allophane and gibbsite. With changing pedogenic environment and weathering intensity, regular variations will occur in clay mineral association in the weathering profile.Based on the micro fabric characteristics of the laterite, the forming mechanism and weathering sequence of the clay minerals are discussed as well. |
