Earth's carbon, derived from planetesimals in the 1 AU region during accretion of the Solar
System, still retains similarities to carbon found in meteorites (Marty et al. 2013) even after …

Carbonatites are familiar to students of petrology as rare igneous rocks formed
predominantly of carbonate, whose only modern expression is a single active volcano that …

The ultimate origin of water in the Earth's hydrosphere is in the deep Earth—the mantle.
Theory and experiments,, have shown that although the water storage capacity of olivine …

Carbon geochemistry of mantle-derived samples suggests that the fluxes and reservoir sizes
associated with deep cycle are in the order of 1012–13gC/yr and 1022–23g C, respectively …

Starting from the late 1980s, several groups of lower-mantle mineral inclusions in diamond
have been found. Three associations were established among them: juvenile ultramafic …

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 …

Tracking the final fate of subducting carbon is crucial to understanding global carbon cycles
and climate changes in the history of the Earth. Available geochemical tracers such as …

Subduction tectonics imposes an important role in the evolution of the interior of the Earth
and its global carbon cycle; however, the mechanism of the mantle–slab interaction remains …

Partial melting in the Earth's mantle plays an important part in generating the geochemical
and isotopic diversity observed in volcanic rocks at the surface. Identifying the composition …

Studies of the inclusions contained in natural diamonds have shown the occurrence of
minerals which must have formed at depths below the lithosphere and which may be closely …
