Eustatic control of turbidites and winnowed turbidites
Geology, 1982Global changes in sea level, primarily the results of tectonism and glaciation, control deep-sea sedimentation. During periods of low sea level the frequency of turbidity currents is greatly increased. Episodes of low sea level also cause vigorous contour currents, which winnow away the fines of turbidites.

Abstract Deep-water sedimentation is currently a major focus of both academic research and industrial interest. Recent studies have emphasized the fundamental influence of seafloor topography on the growth and morphology of submarine ‘fans’: in many turbidite systems and turbidite hydrocarbon reservoirs, depositional system development has ...

Vacillatory turbidites, Barbados
Sedimentary Geology, 1988Abstract A vacillatory turbidite is one containing Bouma sequence divisions that repeat within a bed; it presumably results from a single flow event or several closely-related events (for example, retrogressive slope failure). The most common vacillations or repetitions in such turbidites on Barbados are between T b and T c intervals (T bcbc , for ...

ABSTRACT Eolian-sand turbidites form a clearly distinguishable "eolomarine" sediment facies. They are almost devoid of gradation, fine fraction, and mica, and have comparatively coarse sand medians. The sands consist predominantly of quartz grains, a significant portion of which show yellowish-red stains and frosted surfaces, both characteristic of ...

Abstract During the past 50 years, the turbidite paradigm has promoted many myths related to deep-water turbidite deposition. John E. Sanders (1926–1999), a pioneering process sedimentologist, first uncovered many of these turbidite myths. This paper provides a reality check by undoing 10 of these turbidite myths. Myth No.
