The results of 63 new radiometric K-Ar ar dating Rb-Sr measurements on metamorphic minerals from the internal units of the Western Alps show Hercynian, Permian, as well as three Alpine age groups. The first of the Alpine ages cover the period ar dating 78 and m. The second group comprises K-Ar 39 to 50 m. The final group includes 15 to 30 m. It is not yet clear which geologic processes have led to this isotope re-equilibration. Large amounts of inherited argon have been found in Alpine metamorphic minerals of the basement rocks.
