metamorphic rocks.
It is assumed that the area north of the longitudinal fault zone was uplifted, bringing deeper metamorphic levels closer to the surface.
Continuous subduction also leads to off-scraping of the metamorphic blocks under low-temperature conditions.
The lower part of the metamorphic sole is composed of kyanite and garnet-bearing mica schist, mica schist, quartzite and marble.
In the southern part of the massif, 'ophiolites' are found as thin slices belonging to higher levels of the high-grade metamorphic unit.
The gravel deposits are made up of relatively well-sorted and rounded metamorphic and volcanic clasts.
This work attempts to define metamorphic conditions through an in-depth study of various types of metamorphosed xenoliths, with various mineral assemblages and their chemical compositions.
The appearance of such almost-parallel folds is surprising as competency contrasts should be low at high-grade metamorphic conditions.
Similarly, recent advances in the understanding of metamorphic differentiation in terms of self-organization are mentioned only briefly.
