Abstract The North China Craton (NCC) has been thinned from> 200 km to< 100 km in its
eastern part. The ancient subcontinental lithospheric mantle (SCLM) has been replaced by …

Volatile elements (water, carbon, nitrogen, sulfur, halogens, and noble gases) played an
essential role in the secular evolution of the solid Earth and emergence of life. Here we …

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 …

Kimberlites are volcanic rocks enriched in CO2 and H2O and derive from the deepest-
sourced melts (up to 300 km) that reach Earth's surface. The mantle processes that generate …

The transport of water from subducting crust into the mantle is mainly dictated by the stability
of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key …

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 high water storage capacity of minerals in Earth's mantle transition zone (410-to 660-
kilometer depth) implies the possibility of a deep H2O reservoir, which could cause …

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 study reevaluates the adiabatic temperature profile of the Earth's mantle. The global
average temperature at the 410‐km discontinuity is estimated to be 1839 (38) K by …

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 …
