Penninic

They were deposited as sediments on the crust that existed between the European and Apulian plates before the Alps were formed.

They are characteristically ophiolite sequences and deep marine sediments, metamorphosed to phyllites, schists and amphibolites.

The following Penninic lithologies are found in the Hohe Tauern window, the Kőszeg Mountains and at the northern boundary of the Alps: It is not clear which of these units can be correlated with the Penninic units of the Western Alps.

The oceanic trench deposits of the Penninic nappes are found through the Alps and called Bündner slates.

The conclusion that can be drawn is that the microcontinent wedged out in the east in the Alpine Tethys Ocean.
