Mineralogical and thermal characterization of kaolinitic clays from Terra Alta (Catalonia, Spain)

This research characterizes the kaolinitic clays from Cretaceous-Paleocene lateritic depòsits of Terra Alta (south Catalonia) to evaluate their possible applications. The outcrops and quarries belong to the Horta de Sant Joan and Pinell de Brai areas. The chemical composition, mineralogy, rheologica...
