Abstract

The AA. show that the Strakhov model is of very limited use for tropical areas where formation of pseudosand is observed. They discuss results based on the Cologne Regolith Database (CRD) that allows to extend simple correlations (e.g. microfabric, volume of pores, degree of crystallization). In the compacted tropical soils, kaolinite and gibbsite, which have crystallized in pseudomorphs on the walls of pores and in the matrix reveal, that both minerals have not been products of the weathering of smectite. In cooperation with crystallization of other substances and the formation of pseudosand these formations are the reason for the high stability of regolith covers
