Sedimentary rock - Wikipedia

Fungi and plants (by their roots) and various other organisms that live beneath the surface can also influence diagenesis. Burial of rocks due to ongoing sedimentation leads to increased pressure and temperature, which stimulates certain chemical reactions. An example is the reactions by which organic material becomes lignite or coal.

Radiolarite - Wikipedia

Radiolarite is a siliceous, comparatively hard, fine-grained, chert-like, and homogeneous sedimentary rock that is composed predominantly of the microscopic remains of radiolarians.This term is also used for indurated radiolarian oozes and sometimes as a synonym of radiolarian earth. However, radiolarian earth is typically regarded by Earth scientists to be the unconsolidated equivalent of a ...

Diagenesis below the surface also has a relationship with the migration. When migration occurs early and precedes episodes of tilting or folding it takes prudence on the possible diagenesis trap (Wilson, H.H., 1975, 1977).
