Tyoe 3 interference pattern of folds in Selcifero limestone, Orto di Donna, Lucca, Italy.
Layers of Selcifero limestone and F1 steeply diping axial planes are refolded by F2 folds with shallowly dipping axial planes giving rise to type 3 interference pattern (Ramsay, 1967). A F1 fold hinge is observable close to the center of the photo highlighted by withish cherts layers with M secondary folds.
