  • The nature of gneiss alteration in Calabria is consistent with the results of most experimental and empirical studies. Fundamental changes in the Sila Massif gneiss characteristics can be related to an initial stage of weathering, mainly involving granular disintegration, and to a later stage during which chemical decomposition prevails. These changes, and the intensity of weathering, are reflected by the coexistence of two rockmicrofabrics, clay-poor and clay-rich, respectively, which substitute the original rock fabric. These microfabrics are a useful tool to discriminate between weathering stages; nonetheless the saprolite microfabrics are useful to gain a better understanding of the processes that control landscape evolution in highly wethered rocks.

Abstract
  • The effects of weathering in a Mediterranean climate on the mineralogy and microfabric of Paleozoic gneiss of the Sila Massif have been studied. The determination of quantitative micropetrographic indices provides a measure of the various stages of weathering. (literal)
