...JOHN E. DAMUTH Abstract The late Quaternary terrigenous sediments of the continental margin and abyssal plains of the western equatorial Atlantic consist predominantly of hemipelagic silty clay rich in organic detritus with interbeds of redeposited silts and sands; deposition was cyclic...

... will migrate in response to hydraulic conditions. Within this zone of mixing, salinity and Mg:Ca ratios may come within the necessary limits to bring about dolomitization by aggrading neomorphic processes. The cyclic recurrence of the transgressive-regressive stratigraphic sequences studied implies...

... and depositional envelopes between beach zones revealed a cyclicity in the offshore-onshore movement of sediment. An intefering effect of two sets of movements was clear. A major transfer of sediments towards offshore with gradual lowering of the beach and fluctuations in the direction of alongshore current were...

... thick, which is referred to as the cyclic member because of the abundance of coarsening-upward cycles, averaging 7.4 m in thickness.Sand beds in the cyclic member can be divided into four lithofacies: (1) A facires dominated by medium- to large-scale planar crossbedding, formed by channel processes...
