Instead of such result the Mid-German Crystalline Rise (MGCR) is expanding through Poland to Moravia only in the form of the outer Rhenohercynian and Sub-Variscan molasse, overthrust on the Bruno-Vistulian foreland (Havlena, 1976; Dudek, 1980).
From the geological point of view it is convincible, that ductile to brittle ductile Moldanubian overthrust representing the sutury created by the collision of two microcontinents, which can be describe on base of the structural and geochemical data (Schulman et al., 2005).
(2) Quartz-controlling fractures, represented by faults, thrust faults and overthrusts. The largest crystal-bearing clefts are located in the overthrusts.
Structurally the Picos de Europa region is characterized by a series of successive folds and overthrusts primarily in east-west and east-southwest directions, with the remains of the overthrusts almost rectilinear and parallel to the major folds.
After the Lower Oligocene the Alpine deformation occurred, with the formation of folds and overthrusts in an east-west direction, and the displacement of the earlier structure.
Kretschmer (1897) was the first to comment on the phyllite and marble overthrusts of the Branna Group.
Many of geologists who have studied this region consider the Ramzova "overthrust" as the border between these units.
The pre-Quaternary structure of the Subsilesian and Silesian units represents a neiodal tectonic level of Alpine type subhorizontally translated overthrusts. This tectonic allochton covers as part of Miocene foredeep, as older, Variscan consolidated tectonic level, which represents a submerged continuation of the Epivariscan platform of the Bohemian Massif.
