This research analyses the genesis of eleven inner gorges that morphologically constitute the lower parts of the Rakitnica Canyon Valley in the Central Dinarides of Bosnia and Herzegovina. The spatial distribution of these 300 m deep fluviokarstic landforms, geomorphically reshaped in a thick, brittle Triassic dolomite and limestone, is directly related to contractional restraining bends of right lateral strike-slip faults. The origin and development of most of the Rakitnica's inner gorges was tectonically directed and controlled by pre-existing subvertical tensional gashes, which is confirmed on the basis of their close position to parent dextral strike-slip faults, orientation of its direction, the sigmoidal shape of the gorge's riverbed and hackles on the lower, intact sides of longer gorges. The morpho-evolution of these narrowest parts of the canyon valley, from Upper Pleistocene to recent time, is characterized by simultaneous transpressional uplifting of the terrain and fluvial downcutting across secondary joint fractures mode I opening.
