This summary paper is vital for understanding the origin of deep-water sandstones,emphasizing sandy-mass transport deposits (SMTD) and bottom-current reworked sands (BCRS),in petroleum exploration and production.This cutting-edge perspective,a pragmatic alternative to the conventional and obsolete turbidite concepts,is crucial because the turbidite paradigm has been built on a dubious foundation without empirical data on sandy turbidity currents in modern oceans.In the absence of evidence for sandy turbidity currents in natural environments,elegant theoretical models and experimental observations of turbidity currents are irrelevant substitutes for explaining the origin of sandy deposits as turbidites in the stratigraphic record.
