The disposition of some stratigraphic horizons shows the existence of a large-scale synformal F2-structure.
Metamorphic porphyroblasts have grown mainly between the two main folding phases F1 and F2. Special attention has been given to the garnet porphyroblasts. Probably two types of garnet are present: a Hercynian garnet and an earlier garnet. There are some indications of a tectonic contact within the schists. Probably schists of Lower Palaeozoic age are overlain by older, polymetamorphic schists.Read More
