A clastic dike is a seam of sedimentary material that fills an open fracture in and cuts across sedimentary rock strata or layering in other rock types. Clastic dikes form rapidly by fluidized injection (mobilization of pressurized pore fluids) or passively by water, wind, and gravity (sediment swept into open cracks).
Clastic dikes (also known as sedimentary dikes) are vertical bodies of sedimentary rock that cut off other rock layers. They can form in two ways: When shallow unconsolidated sediment is composed of alternating coarse-grained and impermeable clay layers the fluid pressure inside the coarser layers may reach a critical value due to lithostatic ...

Nov 10, 2020 · Badlands National Park. Clastic dikes are geologic structures which support many of the peaks in the Badlands. NPS Photo. On This Page. What’s in a name? What is a clastic dike? The secret is in the name: they are dikes made up of clasts. Dike: a vertical sheet that cuts through horizontal rock.
Clastic dykes ( Fig. 23) are seams of clastic material that cut across layered strata, usually at a steep angle. There are two main formational mechanisms proposed for clastic dykes. The first suggests that they form rapidly by fluidized injection due to over pressure. The second suggests that sediment was washed or blown into pre-existing facies.

Apr 29, 2024 · Sedimentary dikes, also called clastic dikes, are formed from sedimentary rock. Dikes frequently intrude on open spaces between rocks, called fissures. A dike will either flow or build up in a fissure, pushing the surrounding rock to the side. A dike is, therefore, younger than the rocks surrounding it.
