Abstract (in english)
   Strain patterns within mantle rocks and surrounding coarse-grained felsic granulites from the Kutna Hora Crystalline Complex in the Variscan Bohemian Massif have been studied in order to assess their strain coupling. The studied rock association occurs within low-strain domains surrounded by fine-grained granulite and migmatite. The Doubrava peridotite contains closely spaced and steeply dipping layers of garnet clinopyroxenite, which are parallel to the NE-SW-striking, high-temperature foliation in nearby granulites, while the Uhrov peridotite lacks such layering. The Spacice eclogite is not associated with peridotite and shows upright folds of alternating coarse- and fine-grained varieties bearing NE-SW-striking axial planes.
