A carbonate debris flow "breccia" or a carbonate turbidity flow debris deposit is simply a submarine geologic formation created when the materials fall down the continential slope from the continential shelf above.
Nobody believed in submarine landslides until 1929 when a series of transcontinental cables were broken by a submarine debris flow in a very sequential order. The abyss is not quiet. These submarine landslides can move large distances creating immense debris or breccia fields, up to 600 kilometers in the case of the cable incident.
A number of off shore platforms were damaged by submarine debris flows during the Hurricane Camille incident of 1969.
Some believe many of these flows are triggered by gaseous hydrates which permeate the continental slopes; small crystals of water and carbon gas which "explode" do-to either disturbance (earthquake) or upon reaching some critical mass. whole sections of a slope can then begin to move, and once they reach the bottom of the bench or slope then accumulate and flow out over the abyss and create the breccia fields that can potentially hold oil and gas someday. Geologists look for these rocks because they are naturally porous and permeable. Oiljob
