DOI: 10.1007/s13146-019-00485-4
Abstract: Degradation, diagenesis, and mineralogical changes in foraminiferal tests are recognized as mechanisms that control their preservation and destruction under the subaquatic/aerial conditions, commonly influenced by processes such as dissolution, abrasion, breakage, and mineralogical replacement. In… read more here.

DOI: 10.1016/j.epsl.2021.117166
Abstract: Abstract Magnesium (Mg) in natural waters plays a critical role in governing carbonate mineral formation, dissolution, and diagenesis. Previous laboratory experiments show that Mg can strongly inhibit direct calcite precipitation as well as aragonite to… read more here.

DOI: 10.1016/j.gca.2018.01.037
Abstract: The measurement of multiply isotopically substituted (‘clumped isotope’) carbonate groups provides a way to reconstruct past mineral formation temperatures. However, dissolution-reprecipitation (i.e., recrystallization) reactions, which commonly occur during sedimentary burial, can alter a sample’s clumped-isotope… read more here.

DOI: 10.1016/j.gca.2021.05.036
Abstract: Abstract Glauconite is an authigenic, iron-rich clay mineral that is abundant in greensands formations worldwide. Evidence from these formations suggests that glauconite is commonly diagenetically converted to carbonate minerals such as siderite, ankerite, and ferroan… read more here.
