Abstract

In the Monte Reventino area of Calabria (southern Italy), minor fold axes provide directional markers on the limbs and in the hinges of major inclined folds formed of mechanically strong greenschist encased in weak serpentinite. These markers show that the opposite limbs of major folds have been rotated in opposite directions during Alpine-age emplacement of an overriding nappe. This fold distortion can be explained by tectonic transport roughly parallel to the axes of the major folds, and the sense of this movement can be determined from the pattern of rotated minor fold axes.
