Carbonate clumped-isotope geothermometry is a tool used to reconstruct formation or (re)equilibration temperatures of carbonate bearing minerals, including carbonate groups substituted into apatite. It is based on the preference for isotopologues with multiple heavy isotopes (for example, 13C16O218O2− groups) to be more abundant at equilibrium than would be expected if all isotopes were randomly distributed amongst all carbonate groups. Because this preference is only a function of temperature… Expand
Mechanism of solid-state clumped isotope reordering in carbonate minerals from aragonite heating experiments
The clumped isotope compositions of carbonate minerals are subject to alteration at elevated temperatures. Understanding the mechanism of solid-state reordering in carbonate minerals is important inExpand

Stable and clumped isotope behaviour over the aragonite-calcite transition: implications for sample prep and proxy interpretation
At the earth’s surface, aragonite is thermodynamically unstable and will readily convert to calcite; this can be accelerated by heating and mechanical stress. In experiments where aragonite isExpand

Kinetic effects during the experimental transition of aragonite to calcite in aqueous solution: Insights from clumped and oxygen isotope signatures
Abstract Paleoenvironmental reconstructions based on the clumped isotopes (Δ47) and traditional isotope (δ13C or δ18O) techniques are often problematic for carbonates that have undergone diageneticExpand
