clastic dike

In the geologic record, these are seen as clastic dikes.

Formal geologic reports of clastic dikes began to emerge in the early 19th century.

Some of the articles referenced here describe lithified clastic dikes.

The origin of the clastic dikes in the Columbia Basin is under debate.

Clastic dikes are found in sedimentary basin deposits worldwide.

Clastic dikes are paleoseismic indicators in certain geologic settings.

Clastic dikes are commonly vertical or near-vertical.

However, clastic dikes are typically produced by seismic disturbance and liquefaction of high water content sediments.

Clastic dike swarms associated with salt dome diapirism are reported from the Dead Sea region.

Clastic dike environments include:

The term has also been applied to soft sediment deformation structures, including sand volcanos, sand blows, and certain clastic dikes.

A clastic dike is a seam of sedimentary material that fills a crack in and cuts across sedimentary strata or other rock types.

Cyclic stresses from large waves can cause wet sediments to fluidize, forming various types of soft sediment deformation features including clastic dikes.

Clastic dikes form rapidly by fluidized injection (mobilization of pressurized pore fluids) or passively by water, wind, and gravity (sediment swept into open cracks).

Tens of thousands of unusual clastic dikes (1 mm-350 cm wide) in Pleistocene sediments of southeastern Washington may be related to loading by outburst floods.

Excellent exposures of the unit (which contains abundant clastic dikes) can be found in roadcuts along Hwy 74 (Heppner Highway) near the ranching community of Cecil, Oregon.

Today, the term describes both sedimentary beds deformed by seismic shaking and associated soft sediment deformation structures formed by shaking that may or may not remain confined to a stratigraphic layer (i.e., clastic dikes or sand volcanos).

The morphology of breccias associated with ore deposits varies from tabular sheeted veins and clastic dikes associated with overpressured sedimentary strata, to large-scale intrusive diatreme breccias (breccia pipes), or even some synsedimentary diatremes formed solely by the overpressure of pore fluid within sedimentary basins.
