Document Summary
Abyssal clay - deep-ocean (oceanic) deposits containing less than 30% biogenous sediment. Often oxidized and red in color, thus commonly termed red clay. Algae - primarily aquatic, eurkaryotic, photosynthetic organisms that have no root, stem, or leaf systems. Aragonite - a form of caco3 that is less common and less stable than calcite. Biogenous sediment - sediment containing material produced by plants or animals, such as coral reefs, shell fragments, and housing of diatoms, radiolarians, foraminifers, and coccolithophores; components can be either microscopic or macroscopic. Calcite - a mineral with the chemical formula caco3. Calcite compensation depth (ccd) - the depth at which the amount of calcite (caco3) produced by the organisms in the overlying water column is equal to the amount of calcite the water column can dissolve. Calcium carbonate - a chalklike substance secreted by many organisms in the form of coverings or skeletal structures.
