Other Abstract

The distributive features of purple rock fragments (≥2mm), genetic charactcristics of skeletic purple soils and their classification status as well as the significance of purple rock fragments in Soil Taxonmic Classification are discussed. Our study shows that purple rock fragments (by volume) are extensively distributed in purple soils and "Purple Paady Soils", especially on hilly crests and triassic Fei Xian Guan formation. But they only have a hardness by Mohs scale of less than 3. So. the subgroup of skeletisole do not exist in Sichuan Province.
