5.SLOPE STABILITY PROBLEMS AND THEIR MITIGATION DURING CONSTRUCTION OF THE EDEN PROJECT IN A WORKED-OUT CHINA CLAY QUARRY IN SOUTH-WEST ENGLAND
6.Compared with red weathering crusts in the south China, where the clay mineral is mainly represented by 1:1 type Kaolinite, the red weathering crusts in the Beidaihe coast have relatively lower levels of mineral evolution, deficient in Si and enrichment in Fe and Al. It is suggested that the red weathering crusts in the Beidaihe coast belong to a sialic weathering crust.
7.Suggestion on marking the used oil regeneration project in China, popularzing rapidly distillation-simple solvent refining-clay finishing. That is XXS new technique, is suited to the conditions of domestic and developing countries.
8.Seven profiles of vertisols, ferrallisols and buddy soils in South-West China were studied for the sakeof geochemical and clay mineral composition. According to element geochemical classification ferrallisols may be classified into allitic soil, also, vertisols had a tendency of allitic weathering. The obvious characteristics of paddy soilswere the relative enrichment of Fe, Mn, Ca.
