A hidden carbon cycle exists inside Earth. Every year, megatons of carbon disappear into
subduction zones, affecting atmospheric carbon dioxide and oxygen over Earth's history …

Minerals included in diamonds provide direct information about the petrologic and chemical
environment of diamond crystallization. They record information relating to local and …

Interactions between crustal and mantle reservoirs dominate the surface inventory of volatile
elements over geological time, moderating atmospheric composition and maintaining a life …

Carbonate, the major carbon reservoir on Earth's surface, can enter into the mantle by
subduction. However, evidence for recycled surficial carbonates in the deep mantle is still …

Geological pathways for the recycling of Earth's surface materials into the mantle are both
driven and obscured by plate tectonics,–. Gauging the extent of this recycling is difficult …

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 …

One of the key scientific questions about diamonds is “how are they formed?” To answer this
question, we need to know the diamond-forming reactions and the physicochemical …

Subduction related to the ancient supercontinent cycle is poorly constrained by mantle
samples. Sublithospheric diamond crystallization records the release of melts from …

The nature and cause of deep earthquakes remain enduring unknowns in the field of
seismology. We present new models of thermal structures of subducted slabs traced to …

Subduction is a key process for linking the carbon cycle between the Earth's surface and its
interior. Knowing the carbonation and decarbonation processes in the subduction zone is …
