“…The weathering profiles have been studied following the methodology proposed by many authors (Gullà and Matano, 1997;Borrelli et al, 2012Borrelli et al, , 2014Perri et al, 2012Perri et al, , 2015 and tested in several weathered profiles of Calabria, in agreement with the well-known classification schemes used for weathered rock masses (Dearman, 1976 , 1981; G.C.O., 1988; G.S.L., 1995). Thus, the weathering degree of a rock is divided into six different classes (I to VI) from the fresh/unweathered bedrock to completely weathered rock/residual soils.…”
