Clastic dikes are typically produced by seismic disturbance of high water content sediments. Examples include sand filled sills and dikes in mudstones injected by fluidized sand from below during a penecontemporaneous earthquake event in the Annedale, Northern Wairarapa, New Zealand tectonic area. Clastic dike swarms associated with salt dome diapirism is reported from the Dead Sea region.
Clastic dikes are used in paleoseismological studies as evidence of ancient earthquakes.
Unusual clastic dikes in southeastern Washington state appear to be related to loading by outburst floods.
