Later, the metasediments were transformed to migmatites and granites. The
regional metamorphism was of dynamotherrnal type in which the temperature
played a dominant role. It is indicated in rocks by the presence of orthoclase,

The maximum temperature reached during metamorphism is more difficult to
assess, as it depends on the postulated origin of the migmatites. It is assumed (F
ig. 7) that the migmatites have originated by metasomatic and metamorphic ...
