Compaction occurs via dewatering, grain-scale deformation, and dissolution. Cementation is the precipitation of mineral cements from fluids. Other processes such as replacement and/or dissolution can be important in some rocks.

Beyond being potentially visually striking features, these structures record processes such as the precipitation of minerals, dissolution, surface processes, and bioturbation.

Replacement occurs when the original organic material is replaced with another material. Molds and casts are void and infills formed after organisms. Recrystallization occurs when a mineral changes to a more stable form. Carbonization happens when all the volatiles are driven off leaving only a carbon film. Permineralization occurs when mineral precipitate into void spaces.
