Abstract
Eclogite, felsic orthogneiss and garnetstaurolite metapelite occur in a 5 km long profile in the area of Miedzygorze in the OrlicaSnieznik dome (Bohemian Massif). Petrographic observations and mineral equilibria modelling, in the context of detailed structural work, are used to document the close juxtaposition of high-pressure and medium-pressure rocks.
The axial planar fabrics developed during upright folding are associated with retrogression of the eclogite under amphibolite facies conditions, and with prograde evolution in the metapelites, associated with their juxtaposition. The shared part of the eclogite and metapelite PT paths during the development of the subvertical fabric reflects their exhumation together.
