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 in… Expand
Restricted internal oxygen isotope exchange in calcite veins: Constraints from fluid inclusion and clumped isotope-derived temperatures
Abstract The distribution of oxygen isotopes between calcite and fluid inclusions has demonstrated utility for reconstructing near-surface calcite precipitation temperatures. For calcite that formed… Expand
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 is… Expand
Equilibrium and non-equilibrium controls on the abundances of clumped isotopologues of methane during thermogenic formation in laboratory experiments: Implications for the chemistry of pyrolysis and the origins of natural gases
Multiply isotopically substituted molecules (‘clumped’ isotopologues) can be used as geothermometers because their proportions at isotopic equilibrium relative to a random distribution of isotopes… Expand
Site-specific equilibrium isotopic fractionation of oxygen, carbon and calcium in apatite
The stable isotope composition of biogenic apatite is an important geochemical marker that can record environmental parameters and is widely used to infer past climates, biomineralization processes,… Expand
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 diagenetic… Expand
Clumped isotope fractionation during phosphoric acid digestion of carbonates at 70 °C
The application of clumped isotopes (Δ47) in carbonate minerals as a sensitive temperature proxy in paleo-environments depends on a well-constrained clumped isotope fractionation for the necessary… Expand
Kinetics of aragonite clumped isotope reordering
Clumped isotope thermometry potentially constrains the growth temperatures of carbonate phases, simple molecular gases, and perhaps other compounds. Aragonite is an attractive target for this… Expand
Tracking temperature and δ18Ofluid evolution during diagenesis with carbonate clumped isotopes
Carbonate clumped isotopes allow to reconstruct the temperature of carbonate mineral formation as well as the δ18O of the precipitating fluids in the temperature range between ambient temperatures… Expand
