Caracterización de rocas calcáreas sobre las que se desarrollan suelos forestales de la Reserva de Grazalema (Cádiz)

Abstract

Continuing with previous works, we study the chemical and mineralogical characteristics of four types of calcareous liassic rocks (calcarenites, laminated limiestones, lump limestones and calcareous marls), on which are developed the forest soils of the Grazalema Reserva (Cadiz, Spain). In all of these are present calcite, quartz and mida, although in different proportions. Moreover, dolomite, is found in the calcarenites and the lump limestones, kaolinite in the laminated and lump limestones and, finally, smectites in the marls.
