The circulation of magma is typically accompanied by the transfer of materials and thermal
energy that can significantly alter the compositions and properties of sedimentary rocks …

The hydration and complexation of metals in hydrothermal fluids are key processes
controlling the mobility of elements in the Earth's crust, leading to the formation of ore …

Earth's deep carbon cycle affects atmospheric CO2, climate, and habitability. Owing to the
extreme solubility of CaCO3, aqueous fluids released from the subducting slab could extract …

This chapter is devoted to the carbon and nitrogen stable isotope compositions of terrestrial
diamonds with a strong focus on monocrystalline diamonds formed in Earth's mantle. The …

Abiotic CO2 reduction on transition metal minerals has been proposed to account for the
synthesis of organic compounds in alkaline hydrothermal systems, but this reaction lacks …

Crucial monitors of operation of deep Earth volatile cycles are the accumulated volatile
masses in the exosphere, particularly when these are compared to outgassing fluxes and to …

Alteration of ultramafic rocks plays a major role in the production of hydrocarbons and
organic compounds via abiotic processes on Earth and beyond and contributes to the …

Fluids in the deep crust and upper mantle appear to have played roles in the long-term
evolution of the subcratonic lithospheric mantle and the stabilities of the continents, in the …

Thermodynamic calculations are an essential tool for many areas of geochemistry.
Thermodynamics provides a framework for the quantitative description and prediction of the …

Subduction zones facilitate chemical exchanges between Earth's deep interior and
volcanism that affects habitability of the surface environment. Lavas erupted at subduction …
