Definition

A marine sediment concept defining how particles accumulate, are reworked, and change after burial on the seafloor. It governs depositional processes, physical properties, and post-depositional reactions measured through cores and laboratory analyses. It does not uniquely identify sources or processes without supporting stratigraphic, mineralogical, and geochemical evidence.

Definition

The mixing and reworking of sediments and soils by the activity of organisms — including burrowing, feeding, construction of galleries, and root growth — that alters particle distribution, porosity, stratigraphy, and biogeochemical gradients.
