| Summary of the main deposit types formed during deposition from sediment
gravity flows (Lowe, 1982). Lines without arrows (i.e., 1 - 2 and 1 - 3)
connect members between whom there probably exists a continuous spectrum
of flow and deposit types but which are not parts of an evolutionary trend
of single flows. Arrows connect members, which may be parts of an evolutionary
continuum for individual flows. The transition from disorganised cohesive
flows (1 and 3) to thick, inversely graded density-modified grain flows
and traction carpets (5) and to turbulent gravely high-density turbidity
currents (6) is speculative but may occur. |
