Small continental lakes of Western Andalusia (geomorphology, soils and quaternaty evolution)

Abstract

In the present paper a synthesis about the pedological and geomorphological researchs in the closed basln phenomenon is carried out. The principal geomorphological aspects is a high carbonate paleotopography that give rise the actual relief and the typical soils catena. In this area the recient but not actual tirsfication phenomenon, soil blackerúng processes and the sandy or silty contamination are used for expalin its quatemary evolution,from humid conditions to actual semiarld environment (to resembling sebkhas).
