Siliceous ooze - Wikipedia
Siliceous oozes are largely composed of the silica based skeletons of microscopic marine organisms such as diatoms and radiolarians. Other components of siliceous oozes near continental margins may include terrestrially derived silica particles and sponge spicules.
6.23: Siliceous Oozes - Geosciences LibreTexts
2021年2月15日 · Siliceous oozes are sediments dominantly composed dominantly of SiO2 (silica). Two dominant groups of organisms that contribute siliceous remains: diatoms and radiolarians. Diatoms are the most common plankton. Diatoms are phytoplankton (single-celled microscopic marine plants).
Siliceous ooze | marine deposit | Britannica
The modern oozes gather in latitudes where high organic productivity of floating planktonic radiolarians and diatoms takes place in the warm surface waters. As individual organisms die, their shells settle slowly to the abyssal…
Biogenous ooze - Wikipedia
The primary types of microorganisms used to classify ooze are radiolarians and diatoms (siliceous), and coccolithophores and foraminifera (calcareous). The presence of these organisms can lead to sub-classifications based upon their dominance.
Biogenic ooze | Sediment Composition & Formation | Britannica
Siliceous oozes are composed of opal (amorphous, hydrated silica) that forms the skeleton of various microorganisms, including diatoms, radiolarians, siliceous sponges, and silicoflagellates.
Ooze | Marine Sediment, Organic Matter & Clay | Britannica
The siliceous oozes include radiolarian ooze, comprising essentially brown clay with more than 30 percent of the skeletons of warm-water protozoa, and diatom ooze, containing the frustules (tiny shells) of diatoms.

How does siliceous ooze accumulate on the seafloor if silica-based residues are dissolved slowly at all depths? Silica tests accumulate faster than seawater can dissolve them. We have an expert-written solution to this problem! Siliceous ooze is particularly abundant on the seafloor at __________ and at __________.

Historical Geology/Siliceous ooze - Wikibooks
In this article we shall consider the origin, deposition and lithification of siliceous ooze. As with calcareous ooze, siliceous ooze is formed from the tests of microorganisms; in the case of siliceous ooze, the organisms come in two varieties, diatoms and radiolarians.
