Figure 10. Paleogeographic scheme showing the foreland basin of the southwestern Siberian craton during the early stage of the collisional phase of its evolution (Late Vendian, early Moshakovsky to early Aisa time). Formation of an anastomosing fluvial plain.
Symbols to Figures 8-12: 1 - basement (socle) of the Siberian craton and of continental terranes accreted onto it in the Vendian; 2 - outline of nascent molasse grabens; 3 - braided fluvial plain; 4 - anastomosing fluvial plain; 5 - glaciofluvial debris cones; 6 - shallow marine (shelf) sedimentary systems; 7 - shallow marine carbonate systems of deglaciation-driven marine transgressions; 8 - coastal and strand plain composed of sand deltas; 9 - inferred ice cap boundary; 10 - stream directions, as inferred from sole marks, plunge of troughs, and cross-stratified series in channel deposits of fluvial molasse assemblages; 11 - directions of clastic fluxes (principal); 12 - same, subsidiary; 13 - marine transgression directions; 14 - boundary of sedimentary cover of the Siberian craton; 15 - cratonic boundary.
