13 p, 1.4 MB Weathering sequences of clay minerals in soils along a serpentinitic toposequence / Hseu, Z. Y. (National Pingtung University of Science and Technology. Department of Environmental Science and Engineering) ; Tsai, H. (National Changhua University of Education. Department of Geography) ; Hsi, H. C. (National Kaohsiung University of Science and Technology. Department of Safety Health and Environmental Engineering) ; Chen, Y. C. (National Pingtung University of Science and Technology. Department of Environmental Science and Engineering)
There has been limited research on clay mineral transformation in serpentinitic soils under humid tropical conditions. In this study, four soil pedons were selected along a toposequence from the summit (Entisol), shoulder (Vertisol), backslope (Alfisol) to footslope (Ultisol) positions to explore the contributions and the significance of landscape and weathering status of serpentinitic rock with regard to clay mineral transformations in eastern Taiwan.
