The Control of Diagenesis and Mineral Assemblages on Brittleness of Mudstones
Frontiers in Earth Science, 2021 The variation in mineral composition will affect the rock brittleness, thus the change of mineral assemblages during diagenesis has a potential control on the brittleness of mudstones.

Numerical simulation of diagenetic evolution and porosity prediction in eastern area of Wushi Sag
地质科技通报, 2022 The commercial oil fields discovered in the eastern area of Wushi Sag in recent years are mainly formed in a complex continental sedimentary environment, which was influenced by the tectonic movement, sedimentation and diagenesis.The reservoir in the ...

Palaeozoic stromatoporoid diagenesis: a synthesis [PDF]
Facies, 2021 AbstractPalaeozoic stromatoporoids, throughout their 100-million + year history (Middle Ordovician to Late Devonian and rare Carboniferous), are better preserved than originally aragonite molluscs, but less well-preserved than low magnesium-calcite brachiopods, bryozoans, trilobites and corals.

The Role of Diagenesis in Shaping the Geochemistry of the Marine Carbonate Record
Annual Review of Earth and Planetary Science, 2020 Carbonate sediments and rocks are valuable archives of Earth's past whose geochemical compositions inform our understanding of Earth's surface evolution.

A PERCOLATION MODEL OF DIAGENESIS [PDF]
International Journal of Modern Physics C, 2002 The restructuring process of diagenesis in the sedimentary rocks is studied using a percolation type model. The cementation and dissolution processes are modeled by the culling of occupied sites in rarefied and growth of vacant sites in dense environments.

Evaluation of pore-throat structures of carbonate reservoirs based on petrophysical facies division
Frontiers in Earth Science, 2023 After complex geological transformation, such as sedimentation, diagenesis, and tectonic transformation, carbonate reservoirs have developed multiple reservoir spaces with significant heterogeneity and various pore-throat structures, including pores ...

Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]
, 2004 The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.

The effects of diagenesis on lithium isotope ratios of shallow marine carbonates
American Journal of Science, 2020 In this study, we present new data on the δ7Li values and Li/(Ca+Mg) ratios of carbonate cores from the Great Bahama Bank (Clino, Unda), a deep water core off of the bank top (ODP Leg 166 Site 1007), and the coralline Key Largo Limestone.
