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

The study of a granitic weathering profile in southern Galicia has shown the presence of smectites, which cannot be explained by poor drainage or by hydrothermal alteration. As the soil is polycyclic, the AA. cannot rule out the possibility

The soils of Galicia, NW Spain, developed on gabbro often include one or more buried profiles. In this paper, the AA. compare chemical and mineralogical data for a modern and a buried soil to clarify the pedogenetic and landscape history on gabbro

The object of this study is to assess the effects of slash-and-burn as traditionally practised in Galicia (northwest Spain), in terms of short-term agricultural benefits and influence on soil erosion and runoff.
