The Ultimate Guide to Bedding Plane Markings- Sed Strat #7 | GEO GIRL

Ever wonder what bedding plane markings are and how they form? Well bedding plane markings are markings on the surfaces and/or soles of bedding planes that form by current action, deformation, or biological activity. In this video, I go over the different types of sole and surface markings formed by currents and deformation. There are two main types of sole markings caused by currents: scour marks and tool marks. Flue casts are common scour marks that have bulbous like noses and indicate flow direction. Tool marks include groove casts, which are lineations that indicate the azimuth of flow but not the flow direction, bounce marks, which are caused by saltating grains, brush marks, which are caused by random brushing of the mud surface by grains carried by a current, prod marks, which are more of a penetration of the mud surface and have an abrupt termination that indicates flow direction, and roll marks which are formed by rolling coiled shells that leave behind impact marks like the tread on a tire. Mud crack casts are also sole markings but are not formed by a current. Mud cracks can become filled with overlain sand that lithifies and preserves a cast of the mud cracks which indicate a subaerially exposed, dry environment. Load casts & flame structures are also sole markings but are caused by deformation rather than a current. Lastly, surface markings include rill & swash marks formed in the swash zones of beaches, and pits formed by rain & hail.
