Anadiagenesis
Definition
An intermediate or deep stage within the general process of diagenesis, characterized by intense structural physicochemical transformations of sediments buried at great depths under increased temperatures and pressures, without reaching metamorphism. This phenomenon involves the recrystallization of clay minerals, massive compaction, deep dehydration, and cementation of interstitial fluids, leading to the definitive lithification of sedimentary rocks.
