The existence of mantle plumes was first proposed in the 1970s to explain intra-plate,
hotspot volcanism, yet owing to difficulties in resolving mantle upwellings with geophysical …

Most diamonds are metasomatic minerals, which means they grew from fluids or melts that
moved through solid mantle rocks and chemically interacted with them. The involvement of …

Constraining the volatile content of magmas is critical to our understanding of eruptive
processes and their deep Earth cycling essential to planetary habitability [R. Dasgupta, MM …

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 …

Most magmatism occurring on Earth is conventionally attributed to passive mantle upwelling
at mid-ocean ridges, to slab devolatilization at subduction zones, or to mantle plumes …

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 …

Deep carbon cycle is crucial for mantle dynamics and maintaining Earth's habitability.
Recycled carbonates are a strong oxidant in mantle carbon-iron redox reactions, leading to …

We hypothesize that trace amounts of phosphides formed in the mantle are a plausible
abiotic source of the Venusian phosphine observed by Greaves et al.[Nat. Astron., https://doi …

Long-lived, widespread intraplate volcanism without age progression is one of the most
controversial features of plate tectonics. Previously proposed edge-driven convection …

The water content in Earth's mantle today remains poorly constrained, but the bulk water
storage capacity in the solid mantle can be quantified based on experimental data and may …
