Synfolding calcite veins in the Holy Cross Mountains Fold Belt, central Poland

摘要: Bedding-parallel calcite veins in Devonian rocks from the southern part of Holy Cross Mountains Fold Belt central Poland occur as tabular bodies on shallow dipping well vertical Late Paleozoic map-scale and mesoscopic fold limbs. The syntaxial antitaxial bedding parallel contain kinematic indicators such rotated blocks, fibre boundary steps, boudin trains, beef-like structures congruous steps. These show a sense movement consistent with flexural slip typical folding resulting buckling during layer-parallel shortening. We propose mechanism gradual formation progression fabric development which is mostly an increasing dip angle limbs their deformation. Textures within point to syntectonic growth buckle Belt.
