Thread:Diagenesis (1)

Diagenesis refers to any physical and/or chemical effects that occur after burial of plant and animal matter. The most common physical change is flattening by the weight of sediment deposited above the buried specimen. Flattening can occur very soon after burial or may take millions of years. The most common diagenetic process is the conversion of aragonite to calcite.
