Examples of deposits related to extrabasinal concentrated flows. a, b Detail (a) and close up (b) of coarse-grained, massive sandstones (F5) with abundant floating coal clasts. The concave outer boundary of coal clast (b) suggests that the coal was poorly consolidated and was early “smashed” by lithostatic pressure; c Coarse-grained sandstones with traction carpets (F4) followed by massive sandstones with “dishes” and coal clasts (F5); d Residual, massive, coarse-grained sandstones (F5) irregularly covered by sediment-laden turbulent flow deposits with segregated coal clasts; e Residual, massive, coarse-grained deposits (F5) preserved at the base of a bypass surface (arrow); f Cross-bedded, coarse-grained sandstones (F6) produced by the reworking of the bypassing SLTF (arrow), after a hydraulic jump. Deep-water deposits from the Eocene Guarico Formation (Venezuela) at Panapo river section. Facies codes are from Mutti 1992
