The process of chemical and physical change in deposited sediment during its conversion to rock.

di′a·ge·net′ic (-jə-nĕt′ĭk) adj.


1. (Geological Science) the sum of the physical, chemical, and biological changes that take place in sediments as they become consolidated into rocks, including compaction and cementation, but excluding weathering and metamorphic changes
2. (Chemistry) chem recrystallization of a solid to form large crystal grains from smaller ones
diagenetic adj


(ˌdaɪ əˈdʒɛn ə sɪs)

It is generally accepted that the preservation conditions of calcitic belemnite rostra, which are distinguished by their original low-magnesium calcite composition, makes them relatively stable and resistant to diagenetic alteration (Veizer, 1974; Sslen, 1989; Podhala et al.
The OS layers have only locally slightly changed in the diagenetic processes, whereas the barren limestone interlayers are strongly enriched with MgO and depleted of CaO that is caused by diagenetic dolomitization.
The role of organic matter in the geosphere is difficult to access isotopically as it results from a complex mixture of source organisms, biosynthetic pathways, and diagenetic transformations.
While kaolinite and smectite minerals may be stable at low temperature, illite and quartz are stable even at higher diagenetic temperatures.

Some diagenetic processes, such as compaction, cementation, dolomitization and bioturbation, were also observed in Amb Formation.
The diagenetic processes that have affected the Arab-D reservoir include dolomitization, leaching and recrystallization, cementation, compaction and fracturing.
Shells undergo diagenetic transfomaation during burial and that transformation tilters surface chemistry and ultimately the dissolvability of the shell mineral.
Diagenetic changes at the nanometre scale can be seen in corals from the Norian, indicating that one must exercise caution when interpreting isotopic data in the fossils.
It is well established that bone is susceptible to diagenetic contamination from the burial environment (Budd et al.
They have further suggested that the variation of Cerium anomalies is influenced by a number of factors, including terrigenous input, depositional environment and diagenetic conditions.
