... The D2 deformation produces NE-SW-trending, SEvergent, closed to isoclinal B2 folds of decimetre to several hundred metres in size. A prominent S2 slaty cleavage is related to these folds as well as a crenulation, which is found in places (Fig. 9). Large amounts of intrusive dolomites are found brec ...
