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 …

The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

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 …

Water-rich regions in Earth's deeper mantle are suspected to play a key role in the global
water budget and the mobility of heat-generating elements. We show that ice-VII occurs as …

Oxygen thermobarometry measurements on spinel peridotite rocks indicate that the oxygen
fugacity at the top of the upper mantle falls within±2 log units of the fayalite-magnetite-quartz …

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 …

Diamond is not a common rock-forming mineral (an exception being “diamondite”; see
Jacob and Mikhail 2022, this volume) nor a common crustal mineral (the exceptions being …

A primary consequence of plate tectonics is that basaltic oceanic crust subducts with
lithospheric slabs into the mantle. Seismological studies extend this process to the lower …

Geothermobarometric calculations for a worldwide database of inclusions in diamond
indicate that formation of the dominant harzburgitic diamond association occurred …

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 …
