Clumped isotope temperature calibration for calcite: Bridging theory and experimentation

Abstract

Clumped isotopes ( 47 ) analysis in carbonates is becoming widespread across the geochemical community as a geothermometer that also allows for the reconstruction of the precipitating fluid 18 O composition. While initial 47 -temperature relationship discrepancies between laboratories have been considerably reduced over the past 10 years, theoretical temperature calibration and laboratory experimental efforts have still not converged to common ground. Moreover, a lack of high temperature anchor points has weakened its application to high temperature calcite formation.
