Example of deposits related to extrabasinal hyperconcentrated flows (facies F2 of Mutti 1992). a, b Mud-rich, poorly sorted sandstones with large coal clasts (arrows). Note that in general these deposits are better sorted than those related to cohesive debris flows due to the lower matrix cohesion in HCF, which limited the support of large clasts. The accumulation over a poorly consolidated substrate results in shale injection (inj). Deep-water deposits from the Eocene Guarico Formation, Venezuela. Coin diameter in both photographs is 25 mm
