Garnet amphibolite bands folded together with gneiss lamellae in tight to isoclina folds are described. A structural analysis shows that the folds were formed during two separate deformation episodes. This conclusion has in particular a bearing on the problem of distinguishing between primary intrusive structures and simple and multiple fold-structures.
