The objectives of this project are to: (1) Characterize the effect of spatial variations in deposition and erosion on the fluid flow, pore pressures and thus the stability of continental slope sediments. (2) Constrain the impact of individual turbidity currents on seafloor evolution. (3) Develop a technique for correlating stratigraphy complicated by spatial variations in sedimentation, erosion...

Rhythmical alternations between limestone and marls characterize the Pabdeh Formation, southwestern Iran. Three intervals of these rhythmites were studied using sedimentary, petrography and geochemical parameters analysis, to unravel the possible mechanisms responsible for the origin of these rhythmites. The microfacies analysis reflects calm deep-water sedimentation that were interrupted by sp...

Turbidity currents distribute sediment across the seafloor, forming important archives of tectonic and climatic change on Earth’s surface. current deposition is affected by seafloor topography, therefore understanding interaction turbidity with topography increases our ability to interpret from stratigraphic record. Here, using Shields-scaled physical models currents, we aim better constrain ef...

Submarine channels deliver globally important volumes of sediments, nutrients, contaminants and organic carbon into the deep sea. Knickpoints are significant topographic features found within numerous submarine channels, which most likely play an role in channel evolution behaviour sediment-laden flows (turbidity currents) that traverse them. Although prior research has linked supercritical tur...
