Experiments show that when magma heats black shale wall-rock, fluids form and mobilize S and Cu, which can then concentrate and form base metal deposits. The fluids also attach to sulphide droplets and cause them to float in the host silicate melt.

Methane clumped isotope thermometry relies on accurate measurements of relative abundances of the doubly-substituted isotopologues 12CH2D2 and 13CH3D. Calibration of the thermometer requires, regardless of the applied technique, i.e., laser absorptio

During the differentiation of arc magmas, fractionating liquids follow a series of cotectics, where the co-crystallization of multiple minerals control the melt compositional trajectories, commonly referred to as liquid lines of descent (LLD). These

Hydrogen isotope ratios (D/H) measured on geological samples are used to trace the pathways of water in magmatic and hydrothermal systems. Interpreting respective isotope data relies thereby on the theoretical and empirical constraints on hydrogen is

Clumped isotope thermometry deals with the relative abundance of molecules that contain more than one of the rare isotopes. For methane, 13CH3D and 12CH2D2 isotopologues have been recently proposed as promising tracers in geological, biogeochemical,

Carbon isotope exchange between carbon-bearing high temperature phases records the carbon (re-) processing in the Earth's interior, where the vast majority of global carbon is stored. Redox reactions between carbonate phases and elemental carbon gove

Carbon isotope fractionation in the CO2–CO–CH4–C system was investigated at 300–1200 °C at near-atmospheric pressures by thermally decomposing a variety of organic materials in sealed quartz tubes. Measured gas speciations correspond well to

Whether in gases or fluids, as solid or liquid carbonates, dissolved in magma or precipitated in its elemental form, carbon is present in every domain on Earth. The pathways of carbon across atmospheric-, surface-, subduction- and deeper reservoirs o

At high temperatures, isotope partitioning is often assumed to proceed under equilibrium and trends in the carbon isotope composition within graphite and diamond are used to deduce the redox state of their fluid source. However, kinetic isotope fract
