Hemipelagic mud
Pelagic sediment or pelagite is a fine-grained sediment that accumulates as the result of the settling of particles to the floor of the open ocean, far from land. These particles consist primarily of either the microscopic, calcareous or siliceous shells of phytoplankton or zooplankton; clay-size siliciclastic sediment; or some mixture of these. Trace amounts of meteoric dust and variable amounts of volcanic … WebNov. 2013–Sept. 20247 Jahre 11 Monate. Amsterdam en omgeving, Nederland.

Web31 jan. 2024 · The majority of high-density sediment gravity flows should contain mud, composed of clay-sized and silt-sized particles, since mud is one of the most common sediment types in the modern ocean and in oceans in the geological past (Flemming, 2002; Schindler et al ., 2015 ).
WebA statistically significant correlation exists. However, when the turbiditic sand and mud layers are omitted and the ages are plotted only against the combined thicknesses of the hemipelagic type B layers, an even stronger correlation is obtained.
