Diatomaceous chert consists of beds and lenses of diatomite which were converted during diagenesis into dense, hard chert.
Early diagenesis in newly formed aquatic sediments is mediated by microorganisms using different electron acceptors as part of their metabolism.
An understanding of the geochemistry of connate fluids is important if the diagenesis of the rock is to be quantified.

It occurs at a temperature above diagenesis ( ~ 200 �C ) and below melting ( > 800 �C ).

Fungi and plants ( by their roots ) and various other organisms that live beneath the surface can also influence diagenesis.
While teeth are more resistant to chemical and physical changes over time, both are subject to post-depositional diagenesis.
Changes at or just beneath Earth's surface due to weathering and / or diagenesis are not classified as metamorphism.
Furthermore, once a sediment is deposited, it becomes subject to cementation through the various stages of diagenesis discussed below.
However, a fraction of siliceous oozes dissolve and reprecipitate as a result of diagenesis to form chert beds or nodules.
