Tempestite

(Silurian dolomite) Tempestites are storm deposits that can be recognized throughout the geologic record. They are studied in the scientific disciplines of sedimentary geology and paleotempestology. The deposits derive their meaning from the word tempest, a violent storm. Tempestites are preserved in a multitude of sedimentary environments, including delta systems, estuarine systems, coastal environments, deep-sea environments, and freshwater lacustrine environments. Tempestites most often form in wave-dominated delta systems and preserve, within the sedimentary record, evidence of events and processes below fair-weather wave base and above storm-weather wave base. They are commonly characterized by hummocky cross-stratified beds that have an erosive base and can form under combined flow regimes. This erosive base is often seen in the form of gutter casts.
