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 …

Phanerozoic orogenic gold mineralization at craton margins is related to the metasomatism
of the lithospheric mantle by crustal material. Slab subduction transfers Au from the crust to …

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 …

Background The increased growth rate of young animals can lead to higher lactation
performance in adult goats; however, the effects of the ruminal microbiome on the growth of …

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 …

The extent to which water and halogens in Earth's mantle have primordial origins, or are
dominated by seawater-derived components introduced by subduction is debated. About …

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

Fluids in the deep crust and upper mantle appear to have played roles in the long-term
evolution of the subcratonic lithospheric mantle and the stabilities of the continents, in the …

Rare high-3He/4He signatures in ocean island basalts (OIB) erupted at volcanic hotspots
derive from deep-seated domains preserved in Earth's interior. Only high-3He/4He OIB …
