Related to diagenesis: catagenesis


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)

the physical and chemical changes occurring in sediments between the times of deposition and solidification.

Early diagenesis of bone and tooth apatite in fluvial and marine settings: constraints from combined oxygen isotope, nitrogen and REE analysis.
Pyrite was probably derived from clastic material, along with many other metals, and hence was transferred to the sulfide phase, along with these metals, by diagenesis.
It is also characterized by sporadic carbonate concretions, which occur preferentially in certain beds, presumably controlled by porosity or permeability variations during early diagenesis.
Stage BC, The transition from stage B to stage BC (brown-cannel coal) indicates to the end of diagenesis and beginning of catagenetic transformation of organic matter.

Although diagenesis is slowed greatly in mineral-bound organic matter, determining the preservadonal state of the residual shell organic matrix becomes increasingly important with increasing age (Robbins & Ostrom 1995).
Interpreting the extent of diagenesis can be crucial for distinguishing information about the time of sediment deposition from secondary processes, and the chronology of diagenesis controls whether the rock could contain oil.
Objective: With this project, called HADES, we aim to provide the first detailed, combined analysis of benthic diagenesis and microbial ecology of some of the deepest oceanic trenches on Earth.
