Figure 4. Paleo-transect across the southern Yenisei-Cis-Sayan foredeep and the Baikit uplift (transverse to the fold-and-thrust belt), modified after [Sovetov et al., 1996]. In late Aleshino time, various stratigraphic horizons of the molasse assemblage started onlapping basement and overlapping the foredeep. Assemblage facies change in the same direction, away from the principal (western) source of material, as the marine basin advances from the north. Reference shallow marine systems correspond to the Chistyakovo-late Vanavara marine transgression. The second major marine transgression (Redkolesnaya) was coeval to an orogenic pulse and to the pre-Oskobinsky break forming on a forebulge (Baikit anteclise). The third marine transgression, predating the pre-Katanga break, terminated in the deposition of a continuous carbonate and carbonate-sulfate cover.
Symbols: 1 - Riphean folded basement. Taseyeva Group. Lower fluvial assemblage, sedimentary systems of (2) braided gravel dominated stream, (3) meandering sand dominated stream and ephemeral branching channels, (4) wandering, meandering, and braided gravel dominated streams, pelite-sand terrestrial delta, and ephemeral (proluvial) streams on the Baikit uplift. (5) Medium- and shallow marine assemblage, sedimentary systems of foreshore and transitional beach zones and distal inner shelf zone. The Upper fluvial assemblage, sedimentary systems of (6) anastomosing pelite-sand dominated stream, (7) low-sinuosity stream with bars. The upper shallow marine assemblage, sedimentary systems: 8 - dominated by deposits of lower and middle foreshore beach zones, 9 - dominated by deposits of the upper foreshore beach zone; 10 - carbonate (stromatolite) and terrigenous carbonate-sulfate supratidal, lagoon deposits of the shelf and shoreline of the forebulge; 11 - carbonate-terrigenous, carbonate, and carbonate-sulfate deposits of the supratidal zone and various parts of the foreshore zone.
