The Miocene deposits of the north-western part of the Ukrainian Fore-Carpathians (PreCarpathians), which are part of the Boryslav-Pokuttya and Sambir advanced tectonic nappes, are considered. An attempt was to reconstruct the sedimentation conditions of the Miocene molasses of this region was made. On the basis of the environmental analysis of foraminiferal associations of the Vorotyshcha and Stebnik formations of the Boryslav-Pokuttya and Sambir nappes, conclusions were made on the conditions of sedimentation of the region in the Carpathian time at the boundary between of the early and middle Miocene and on the conditions oa accumulation of the Berezhnytsa Formation of the Sambir Nappe at the end of the middle – at the beginning of the late Miocene. Deposits were formed in marine basin at the shelf depths with normal salinity or close to it.
