Periadriatics
As Periadriatika (also lat. Periadriatica ) are plutonic rocks which have in the region of the Periadriatic seam between the rock formations of Südalpen have risen.
These periadriatic intrusives are mainly granites and tonalites . A distinction is made between an older (pre- or old Alpid ) phase of intrusions and a more recent one, which is related to the formation of the Alps.
Larger formations are u. a. in the Adamello and Presanella groups , also in the Sarntal Alps , on the southern edge of the Zillertal Alps and the Hohen Tauern ( Rieserferner group ) and the Kreuzeck group . The melting and metamorphosis of some older crystalline rocks, for example in the Gail valley and on the southern edge of the Hohe Tauern, is attributed to the contact with the plutonic past .
