Abstract

A chevron-folded phyllite composed of well contrasted quartzose and micaceous layers was examined. The false cleavage in the mica layers is of fan type and measurements show a correlation between the angle of the fan and the thickness of the layer in which it forms. Such a correlation is to be expected if the folds formed by buckling under lateral compression.
