Microscopic study of twelve weathering profiles developed on granitic rocks in Galicia (NW Spain) showed that, in most cases, the transformation of the parent rock into saprolite occurs with pseudomorphic alteration of the plagioclases
Micromorphology is the best technique to characterise the formation and evolution of parent materials and soils in terms of chronology and macro horizon sequence. This paper attempts to elaborate a higher level classification system for microfabrics
