The predominance of ripple-like features, fining-up sequences, strong alignment of allochems, and parallel-laminated beds within facies 5 indicates a gentle reworking by bottom currents and deposition of a muddy to sandy contourite.
The apron is composed of debris-flow deposits and distinct oolitic turbidite units that are laterally extensive, interbedded by mudstones and packstones interpreted to be possible contourite deposits.

This is an antidote, he says, to the current complacency-ridden interpretation of deep-water sands based on turbidite and contourite facies models.

The first five papers are largely about the economic interest in contourites and include discussion of North Atlantic contourite sand channels, the Quaternary evolution of the countourite depositional system in the Gulf of Cadiz, and bottom-current reworked Paleocene-Eocene deep-water reservoirs of the Campos Basin of Brazil.
The recognized sequence of structures in the calcarenite beds allowed us to conclude that each of these beds was deposited by contourite currents.
The turbidite intercalations are scarce, but they are distinctively different of the contourite beds that characterize the underlying unit.
In Caravaca, the onset of contourite deposition could reflect the changes that are occurring in the basin.
In the second interval (early Maastrichtian) these hemipelagic conditions persisted, although the sedimentation was strongly influenced by deep semi-permanent bottom currents which generated contourite facies.
