Novel Mixed Sand-Mud Bedforms, Cohesive Sediment Gravity Flow Behaviour, and Submarine Fans

Explore novel mixed sand-mud bedforms and their implications for submarine fan environments in this 50-minute lecture. Delve into the unique shapes and sizes of these bedforms compared to pure-sand formations, and understand their significance in reconstructing sedimentary processes. Learn about the role of cohesive clay in producing transient-turbulent fluid dynamics in sediment gravity flows. Examine the Aberystwyth Grits Group and Borth Mudstone Formation as case studies. Discover methods for sedimentary logging, analyzing current ripples, and interpreting bed-waves. Investigate spatial distribution patterns of bedforms and their use in inferring flow processes. Gain insights into hybrid event beds and their importance in fan fringe environments. Enhance your understanding of sedimentology and its applications in interpreting ancient and modern depositional settings.
