Kinematic analysis of deformed quartzite from the Vysoký kámen: implications for development of the Saxothuringian orogenic wedge
 Ildžová, Tamara ; Jeřábek, Petr (advisor) ; Jouvent, Marine (referee)
The Saxothuringian orogenic wedge is an impressive example of a collisional orogenic wedge formed during the Variscan orogeny in the Bohemian Massif. The Vysoký kámen area in the Erzgebirge Mountains (Saxothuringian Domain) represents a part of the outer wedge which was not subducted into the great depths during the evolution of the wedge. To better understand a polyphase deformation in this frontal part of the former accretionary wedge, the study focuses on macro and micro-scale analyses of deformed quartzite and quartz veins from the Vysoký kámen area. Two main deformation fabrics (S1 and S2) were formed under slightly different P-T conditions and linked to two deformation events (D1 and D2). The S1 fabric defined by coarse-grained recrystallised quartz grains and by axial planes of folded quartz veins is related to a simple shear regime but also shows stretching in the folds axes in the NS direction. This subhorizontal and gently eastward dipping metamorphic foliation is associated with deformation event D1 during which the area subducted. Minerals such as paragonite and rutile, and a higher silica content up to 3.17 a.p.f.u. recorded in micas reflect a subduction environment. The second deformation fabric S2, characterised by fine-grained recrystallisation, is generally identified as...
