Kinetic effects during the experimental transition of aragonite to calcite in aqueous solution: Insights from clumped and oxygen isotope signatures

Y Guo, W Deng, G Wei - Geochimica et Cosmochimica Acta, 2019 - Elsevier
Paleoenvironmental reconstructions based on the clumped isotopes (Δ 47) and traditional
isotope (δ 13 C or δ 18 O) techniques are often problematic for carbonates that have …

Mg structural state in coral aragonite and implications for the paleoenvironmental proxy

AA Finch, N Allison - Geophysical Research Letters, 2008 - Wiley Online Library
Thermodynamic calculations and inorganic precipitation experiments indicate a relationship
