Deposition of ungraded muds from high-density non-turbulent turbidity currents

Abstract

Turbidity current deposits of mud have recently been found up to 10m in thickness resulting from single depositional events1,2. Turbidites 1–5 m thick from the Madeira Abyssal Plain3,4 display long segments with little vertical change of grain size5,6. This suggests that the currents 'froze' in some way, making them unable to sort sediment. Here we suggest… (More)
