A turbidite is the geologic deposit of a turbidity current, ... Sedimentology of the Grès d'Annot Formation, Thesis: Technische Universität Clausthal, Germany ...
Turbidite interbedded with finegrained dusky-yellow sandstone and gray clay shale that occur in graded beds, Point Loma Formation, California. When the energy of a turbidity current lowers, its ability to keep suspended sediment decreases, thus sediment deposition occurs.
Steeply-tilted layers of flysch on the coast of Bay of Biscay, at Zumaia, Basque Country, Spain. Flysch (/ f l ɪ ʃ /) is a sequence of sedimentary rock layers that progress from deep-water and turbidity flow deposits to shallow-water shales and sandstones.
Turbidite from the Devonian-age Becke-Oese Sandstone, Germany showing a complete Bouma sequence.. The Bouma sequence (named after Arnold H. Bouma [], 1932–2011 [1]) describes a classic set of sedimentary structures in turbidite beds deposited by turbidity currents at the bottoms of lakes, oceans and rivers.

Turbidites in the Venado Sandstone (Great Valley Sequence) at Lake Berryessa, California.. The Great Valley Sequence of California is a 40,000-foot (12 km)-thick group of related geologic formations that are Late Jurassic through Cretaceous in age (150–65 Ma) on the geologic time scale.
Bioclastic formations are of organic sources, such as biochemical chert, which forms from siliceous marine organism decay and diagenesis. Organic sedimentation of parent material from decaying plant matter in bogs or swamps can also result in a graded bedding complex. This activity leads to formation of peat or coal, after thousands of years.
The Lowe sequence adds three layers labelled S1 through S3 to Bouma's terminology, with S1 being at the bottom and S3 at the top of a sandy turbidite bed. As with the Bouma sequence, each layer has a specific set of sedimentary structures and lithology .
