Annotation:
Sedimentary-facial models of Paleozoic subsalt deposits of Orenburg Region built on the basis of chronostratigraphic analysis are considered. The analysis allowed to identify the rock units (Ordovician-Low-Devonian (pre-Emian), Emian-mid-Devonian, Fransko-Turnian, Vesian-Bashkirian, Moscow-upper-Carboniferous, low-Permian) which genetically interconnected by unity and directivity of sedimentation and separated by surfaces of regional discordance the formation of which in turn is caused by global falls of the sea level and (or) structural change of the area in question
