Surface consolidation of natural stone materials using microbial induced calcite precipitation [PDF]
, 2014 Natural stone tends to have high porosity and is easily eroded by environmental weathering. In recent years, industrialisation has caused an acceleration of stone decay due to the toxic by-products of industry breaking down the stones’ constituents ...

Testing the impact of diagenesis on the delta O-18 and delta C-13 of benthic foraminiferal calcite from a sediment burial depth transect in the equatorial Pacific [PDF]
, 2013 Stable oxygen and carbon isotope (O-18 and C-13) values measured in foraminiferal calcite are one of the primary tools used in paleoceanography. Diagenetic recrystallization of foraminiferal calcite can act to reset primary isotopic values, but its ...

Evaluating the Effect of 18O Incorporation on the Vibrational Spectra of Vaterite and Calcite
Crystals, 2022 Calcium carbonates are critical in biomineralization processes and as functional materials. For many applications, isotope enrichment in these materials allows researchers to monitor reaction pathways and retrace environmental signatures.

High P-T Calcite-Aragonite Phase Transitions Under Hydrous and Anhydrous Conditions
Frontiers in Earth Science, 2022 The subduction of calcite into deep Earth and subsequent phase change are important for global carbon cycle. However, the study of the phase boundary between calcite and aragonite under high P-T conditions is insufficient due to sparse existing phase ...

Bromate incorporation in calcite and aragonite
, 2021 The presence of bromine as a trace-element in calcium carbonate speleothems constitutes a useful proxy of past volcanic activity, thus helping to provide input parameters for climate model simulations and risk assessment.
