terrigenous sediment

Terrigenous sediments is the most abundant sediment found on the seafloor.

The remaining 14% is layered with terrigenous sediments.

Other sources of terrigenous sediment may include airborne and seaborne volcanoclastic debris.

The continental shelves are covered by terrigenous sediments; that is, those derived from erosion of the continents.

Carbonate platforms formed during the early Cretaceous and were covered by terrigenous sediments toward the late Cretaceous.

Terrigenous sediment supply to the deepwater bottom-currents and to the nepheloid layer primarily depends on climate and tectonics in the continental environment.

In oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, that are derived from terrestrial environments.

Sources of terrigenous sediments include volcanoes, weathering of rocks, wind-blown dust, grinding by glaciers, and sediment carried by icebergs.

Terrigenous sediments that eroded from Paleozoic rocks, and weakly metamorphosed sedimentary rocks from the Ouachita Mountains in Oklahoma constitute a large part of the Woodbine.

For instance, terrigenous sediments and nutrients carried by freshwater runoff are first filtered by coastal forests, then by mangrove wetlands, and finally by seagrass beds before reaching coral reefs.

Diamicton (also diamict) is sediment that consists of a wide range of nonsorted to poorly sorted terrigenous sediment, i.e. sand or larger size particles that are suspended in a mud matrix.

To the west, the Apulia Platform plunges downfaulted underneath the terrigenous sediments of the Apennine foredeep; to the southeast, the Jurassic-Early Cretaceous margin lies 20-30 km offshore from the present Apulia coastline.

Near the continental margins sediment is terrigenous, meaning derived from the land, unlike deep sea sediments which are made of tiny shells of marine organisms, usually calcareous and siliceous, or it can be made of volcanic ash and terrigenous sediments transported by turbidity currents.
