WebDiagenesis. Diagenesis is the change of sediments or existing sedimentary rocks into a different sedimentary rock, mineral, or texture. It can occur during or after rock formation (lithification) at temperatures and pressures less than less than those for metamorphic rocks. Diagenetic conditions can occur at the surface or underground up to a ...

WebApr 6, 2024 · Three major geologic stages determine the porosity of carbonate rocks: [1] Predepositional. Depositional. Postdepositional. The predepositional stage is the time from when sedimentary material first forms to when it is finally deposited. Porosity created during the predepositional stage is mainly chambers or cell structures of skeletal grains ... WebJan 1, 2003 · Furthermore, because many primary carbonate grains are composed of unstable minerals (especially aragonite and high-Mg calcite), diagenetic alteration commonly is quite extensive in carbonate rocks. The variability of inorganic and biogenic carbonate mineralogy through time, however, complicates prediction of patterns of … WebMay 12, 2024 · In many mineral systems, carbonate minerals constitute a significant proportion of the host rock and gangue mineralogy. Complex carbonate parageneses are often found in ore deposits hosted in sedimentary rocks (Cline et al. 2005; Hitzman et al. 2005; Leach et al. 2005), and can derive from detrital, diagenetic, hydrothermal, and … ffvb volley assis
