"DIAGENESIS" is a common misspelling or typo for: diagnosis, digenesis.

Specialty Definition: DIAGENESIS

Domain	Definition
Geological	A group of processes that cause physical and chemical changes in sediment after it has been deposited and buried under another layer of sediment. Diagenesis may culminate in lithification of sediment, turning it into solid rock. (references)
Mining	Any change occurring within a sediment after its deposition and during and after its lithification, exclusive of weathering. It includes such processes as compaction, cementation, replacement, and crystallization,under normal surficial conditions of pressure and temperature. (references)

Specialty Definition: Diagenesis

(From Wikipedia, the free Encyclopedia)

With regards to the Earth Sciences, diagenesis refers to all the chemical, physical, and biological changes undergone by a sediment after its initial deposition, and during and after its lithification, exclusive of surface alteration (weathering). Diagenesis is the lowest grade of metamorphism.

The study of diagenesis in rocks is used to understand the tectonic history they have undergone, the nature and type of fluids that have circulated through them and, from an economic standpoint, allows the assessment of the likelihood of finding various economic minerals and hydrocarbons.

The role of diagenesis in hydrocarbon generation

When animal or plant matter is buried during sedimentation, the constituent organic molecules (lipids, proteins, carbohydrates and lignin-humic compounds) break down due to the increase in temperature and pressure. This transformation occurs in the first few hundred metres of burial and results in the creation of two primary products: kerogens and bitumens.

It is generally accepted that hydrocarbons are formed by the thermal alteration of these kerogens (the biogenic theory). In this way, given certain conditions (which are largely temperature-dependent) kerogens will break down to form hydrocarbons though a chemical process known as cracking, or catagenesis.
