Early Pleistocene Mud Tectonics and Sedimentation Within Mud-Withdrawal Basins, Bawdsey, Suffolk, UK
Seds Online via YouTube
Overview
Explore the fascinating world of Early Pleistocene mud tectonics and sedimentation in mud-withdrawal basins through this comprehensive lecture. Delve into the deposition of basal Pleistocene warm-water clastics on Paleocene-Eocene marine mudrocks, triggering intense syndepositional mud tectonics. Examine the formation of subsiding mud-withdrawal basins, rising mud diapirs, and mud ridges. Investigate various mud deformation processes, from plastic flow to liquefied flow, and the extrusion of allochthonous mud sheets. Learn how tidal bedforms in the Red Crag provide insights into deposition duration and mud mobilization. Discover the impact of mud dewatering on sediment color and the geometry of fluid-escape pathways. Understand the significance of this syndepositional deformation, previously misinterpreted as postdepositional cryoturbation, and its implications for civil engineering projects. Explore topics such as the North Sea Basin, London Clay Formation, tidal sediments, quick clay, and the Risa failure. Gain insights into the importance of this research for large engineering projects like offshore windfarms and nuclear power stations. Engage with in-depth discussions on mud composition, organic matter, unconformity, basal contact, polygonal fractures, mineralogy, and fluid pressure gradients.
