Diagenesis - Wikipedia

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.

Diagenesis | geology | Britannica

Diagenesis is considered a relatively low-pressure, low-temperature alteration process, whereas metamorphism is considered to be a rock-alteration process occurring at relatively higher pressures and temperatures. An example of diagenesis is the chemical alteration of a feldspar to form a distinctly new mineral in its place, a clay mineral.

Carbonate diagenetic stages - AAPG Wiki

Solution by meteoric water creates porosity. Internal sedimentation and cementation by precipitation from solution destroy porosity. Path of diagenesis. The parts of the path of diagenesis that a carbonate sediment follows determine the evolution of its porosity. Figure 2 summarizes the diagenesis that occurs along the path. See also

Carbonate Sedimentation and Diagenesis in the Evolving ...

Carbonate Sedimentation and Diagenesis in the Evolving Precambrian World - Precambrian carbonates are usually regarded at the simple cousins of the sedimentary realm, composed of stromatolites and dolostones, texturally not challenging and commonly altered beyond recognition by the vagaries of time, diagenesis and metamorphism.

Geology 135 Sedimentation - Diagenesis

Geol 135 Sedimentation. J Bret Bennington. Updated 10/99. Diagenesis. Diagenesis – postdepositional modification of sedimentary layers by both physical and chemical processes. Diagenesis grades into metamorphism, the boundary between the two defined by a temperature – pressure line.

The Chalk Sea – sedimentation and diagenesis

Chalk sedimentation, and subsequent diagenesis, were partly controlled by orbital cyclicity which created the regular rhythmicity so commonly seen in chalks, and for this reason individual beds can extend over great distances.

Carbonate diagenesis - AAPG Wiki

Diagenesis. The reservoir quality of sediments is modified by diagenetic processes. Some diagenetic processes are directly related to the physical nature of the sediment, and the resulting geometries can be directly related to sedimentation patterns. Other diagenetic processes involve the interaction of sediment with flowing interstitial water.

Diagenesis - Wikipedia

Diagenesis (/ ˌ d aɪ ə ˈ dʒ ɛ n ɪ s ɪ s /) is the process that describes physical and chemical changes in sediments caused by increasing temperature and pressure as they get buried in the Earth's crust. In the early stages, this transformation of sediment into sedimentary rock, (lithification) is accompanied simply by a reduction in porosity, while its component mineralogy remains ...
