Emerging stable isotope techniques in hydrothermal research: new methods applied to carbonates and hydrous minerals in ore deposits and geothermal fields
Over the last 70 years, stable isotopes have provided critical insight into the processes governing transfer of mass and energy through geologic systems. Significantly, isotopic signals in minerals reflect conditions of crystallisation, and subsequent alteration history. In hydrothermal systems, …

Methane cold seeps: Paleo proxies, modern measurements, and instrument development
… reactive-transport model, I show that the clumped isotopic composition of MDACs (the frequency of 13C–18O bonding within the carbonate lattice) quantitatively records AOM rates (Chapter 2) and derived global estimates of AOM rates at both modern seeps and over the past as recorded in MDACs. …

Reconstructing Australia’s late Quaternary climate from the geochemistry of lake sediments and snail shells
… quantitative temperature estimates, based on the clumped isotope composition (Δ47) of freshwater snail shells from Blanche Cave, also in south-eastern Australia (Chapter 6). Δ47 analysis allows calculation of the growth temperature of carbonate minerals (e.g. snail shells), independent of …
