Fotographs and interpretations of key observations. The stratigraphic younging direction is upwards in all pictures. For outcrop locations see Fig. 2a. a Remnants of tight to isoclinal F1 folds and penetrative S1 axial planar cleavage in the Drina-Ivanjica Paleozoic (outcrop 006). b WNW-verging tight to isoclinal F1 folds in competent marble layers in the Drina-Ivanjica Paleozoic (outcrop 032). c Thin section from outcrop 006 (Drina-Ivanjica Paleozoic) showing buckling of the S0 bedding plane and related S1 axial planar cleavage defined by solution surfaces. d Subgrain formation and grain boundary migration of quartz during D1 phase in thin section from outcrop 169 (Drina-Ivanjica Paleozoic). e Tight to isoclinal F1 folds and related S1 axial planar cleavage in the Northern Triassic unit at outcrop 198. f Thin section from the Southern Triassic unit showing preserved carbonate texture and the lack of D1 deformation structures (outcrop 026)
