The two primary types of ooze are siliceous, which is composed primarily of silica (SiO 2), and calcareous or carbonate, which is mostly calcium carbonate (CaCO 3). [1] In an area in which biogenous is the dominant sediment type, the composition of microorganisms in that location determines to which category it is classified.
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
Siliceous ooze is a type of biogenic pelagic sediment located on the deep ocean floor. Siliceous oozes are the least common of the deep sea sediments, and make up approximately 15% of the ocean floor. [1] Oozes are defined as sediments which contain at least 30% skeletal remains of pelagic microorganisms. [2]
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.

Fluvial sediments are transported from land by rivers and glaciers, such as clay, silt, mud, and glacial flour. Aeolian sediments are transported by wind, such as dust and volcanic ash. [8] Biogenous sediment is the next most abundant material on the seafloor. Biogenous sediments are biologically produced by living creatures.
The mining robots operating on the seabed floor emit plumes of sediment, which could cover fauna in the area around the mining site and therefore have a great impact on the ecosystem of the seabed. [33] The produced plumes contain a mixture of dissolved material and suspended particles of a range of sizes.
Turbidite sequences are classic hosts for lode gold deposits, the prime example being Bendigo and Ballarat in Victoria, Australia, where more than 2,600 tons of gold have been extracted from saddle-reef deposits hosted in shale sequences from a thick succession of Cambrian-Ordovician turbidites.
