  Unravelling calcite-to-aragonite evolution from a subsurface …

  20231220 · The calcite-to-aragonite transition is thus controlled by the reaction kinetics and mechanisms of Mg-calcite formation and the chemical evolution of the precipitating solution at the nano- to micro-spatial scale, creating Mg-enriched HMC surface sites for aragonite to be nucleated and preferentially grown.

  Effect of aragonite to calcite transformation on the …

  201941 · As in the stage before, after aragonite formation, calcite started to nucleate and the subsequent advance of the recrystallization process partially transformed the aragonite leaving relicts and producing the aragonite rim …

  Calcite: Mineral information, data and localities.

  Calcite-Rhodochrosite Series. A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varieties. NOTE on the unit cell and the Miller indices ...

  The impact and implications of aragonite-to-calcite transformation …

  2021111 · Abstract Trace elements in cave carbonates (both calcite and aragonite) have been considered major proxies in paleo-hydroclimatic research. However, their imprints in authigenic minerals might be altered by neomorphic processes (e.g., aragonite-to-calcite transformation). Therefore, it is crucial to understand the impacts of neomorphism on the …

  Calcium Isotopic Constraints on the Transition From Aragonite …

  202252 · Here, we employed a multi-proxy geochemical and petrographic approach, including measuring the Ca isotope (δ 44 Ca) and Sr content of Ediacaran–Cambrian carbonates, to provide new insights into the timing of the transition from a “dolomite-aragonite sea” to a “calcite sea” across the Ediacaran-Cambrian transition.
