These new data support an interpretation whereby the locus of mylonitization in the MCT zone propagated southward into progressively cooler crustal material.
The mylonitization of the rocks at Prague fault zone indicates former tectonic movements (Kriz, 1999).
The partial overthrust accompanied by mylonitization or/and boudinage exists in individual slices as well.
