Tempestite
Tempestite is a storm deposit.
Tempestites are rocks which show evidence of a strong storm, which has redeposited pre-existing sediments. They occur in shallow-water conditions, because these sediments are disturbed and redeposited by the energy of waves. The scientific study of tempestites is called paleotempestology.
