Flame StructuresNamed for their flame like appearance, these structures are formed due to soft-sediment deformation. The precursor to these formations occurs when a layer of unconsolidated sediment is overburdened with a layer of sediment with a higher density or a greater pressure. The instability in these layers require two things to relieve the stresses, to be completely water saturated and also a triggering event. The water facilitate the movement of sediments, whereas the trigger initiates the process. This trigger can be an earthquake, resulting in wide spread formations, or even movement of waves above, creating a localised events. With this initiation the lower sediments are injected into the upper layer and the upped layer sags into the lower (called Load Casts), accommodating for the instability.-JCReference: https://blogs.egu.eu/divisions/ts/2016/10/17/soft-sediment-structures-slumps-and-flames/Image credit: https://bit.ly/2JK4mq2https://bit.ly/2Nynnhi -- source link
