Abstract
Field, petrographic and quantitative strain analysis have been performed on highly foliated limestones outcropping in northern Calabria and generally attributed to two distinct units (San Donato and Pollino) on the basis of presence/absence of metamorphism. The deformation, however, is comparable in all the studied outcrops indicating that the widely accepted distinction of units in the area should be revised. Deformation is very localized in narrow ductile shear-zones affecting Tertiary conglomerates and Jurassic oncoidal packstones. The former are more strained because of their closeness to siliciclastic beds. The main deformation mechanism was grain boundary sliding with minor intragranular strain and pressure solution.
