A middle to upper Miocene turbidite depositional system exists at Site 765 in the southeastern Argo Abyssal Plain, along the northwest margin of Australia. Turbidites consist predominantly of planktonic calcareous components. Textural, mineralogical, bedding, and downhole logging trends within the system support the idea of a rapid progradation of the turbidite system in the middle to late Miocene. The onset of abundant turbidity currents into the area is attributed to changes in oceanographic conditions that...
