Abstract

The paper reports interdisciplinary research of weathering profile stages on gneiss with regard to tectonic and landscape evolutions of the western Sila Grande Massif (Southern Italy). The outcropping rocks consist of medium- to coarse-grained biotite–garnet and sillimanite gneiss (BGS-G), and medium- to coarse-grained biotite–muscovite migmatitic gneiss (M-G). The weathering processes produced phyllosilicates and Fe-oxides; neoformed clay minerals and ferruginous products replaced feldspars and biotite during the most advanced weathering stage. Microfractures and morphological variations occur on the original rock and, thereby, affect the surrounding landscape processes. The weathering profile mineralogy and rock textures viewed in the context of landscape evolution provide useful insights into the widespread slope movement phenomena in the Sila Grande Massif gneiss
