Slab melting boosts the mantle wedge contribution to Li-rich magmas
The lithium cycling in the supra-subduction mantle wedge is crucial for understanding the generation of Li-rich magmas that may potentially source...

Seismicity at the Castor gas reservoir driven by pore pressure diffusion and asperities loading
The 2013 seismic sequence at the Castor injection platform offshore Spain, including three earthquakes of magnitude 4.1, occurred during the initial...

Non-KREEP origin for Chang’e-5 basalts in the Procellarum KREEP Terrane
Mare volcanics on the Moon are the key record of thermo-chemical evolution throughout most of lunar history
1 –3 . Young mare basalts—mainly distributed...

Petrogenesis of isotopically enriched Quaternary magma with adakitic affinity associated with subduction of old lithosphere beneath central Myanmar
We present a model for the petrogenesis of magma with adakitic affinity in an old subduction zone, which does not involve slab melting and is...

A temperate Earth-sized planet with tidal heating transiting an M6 star
Temperate Earth-sized exoplanets around late-M dwarfs offer a rare opportunity to explore under which conditions planets can develop hospitable...

Europium in plagioclase-hosted melt inclusions reveals mantle melting modulates oxygen fugacity
To gain insights into the composition and heterogeneity of Earth’s interior, the partial pressure of oxygen (oxygen fugacity, or f O 2 ) in igneous...

Crustal processes sustain Arctic abiotic gas hydrate and fluid flow systems
The Svyatogor Ridge and surroundings, located on the sediment-covered western flank of the Northern Knipovich Ridge, host extensive gas hydrate and...

New identification and significance of Early Cretaceous mafic rocks in the interior South China Block
Early Cretaceous mafic rocks are first reported in the northern Guangxi region from the western Qin-Hang belt in the interior South China Block. A...

Rapid shifting of a deep magmatic source at Fagradalsfjall volcano, Iceland
Recent Icelandic rifting events have illuminated the roles of centralized crustal magma reservoirs and lateral magma transport
1 –4 , important...

Hydrous mantle plume promoted the generation of continental flood basalts in the Tarim large igneous province
Recent research on the water content of large igneous provinces (LIPs) has revealed that water has a significant impact on the formation of LIPs....

Potassium isotope heterogeneity in the early Solar System controlled by extensive evaporation and partial recondensation
Volatiles are vital ingredients for a habitable planet. Angrite meteorites sample the most volatile-depleted planetesimal in the Solar System,...

Fully fluorinated non-carbon compounds NF3 and SF6 as ideal technosignature gases
Waste gas products from technological civilizations may accumulate in an exoplanet atmosphere to detectable levels. We propose nitrogen trifluoride...

A HIMU-like component in Mariana Convergent Margin magma sources during initial arc rifting revealed by melt inclusions
Compositions of island arc and back-arc basin basalts are often used to trace the recycling of subducted materials. However, the contribution of...

Fluxing of mantle carbon as a physical agent for metallogenic fertilization of the crust
Magmatic systems play a crucial role in enriching the crust with volatiles and elements that reside primarily within the Earth’s mantle, including...

Sublithospheric diamond ages and the supercontinent cycle
Subduction related to the ancient supercontinent cycle is poorly constrained by mantle samples. Sublithospheric diamond crystallization records the...

Eoarchean and Hadean melts reveal arc-like trace element and isotopic signatures
Constraining the lithological diversity and tectonics of the earliest Earth is critical to understanding our planet’s evolution. Here we use detrital...

Hydrothermal 15N15N abundances constrain the origins of mantle nitrogen
Nitrogen is the main constituent of the Earth’s atmosphere, but its provenance in the Earth’s mantle remains uncertain. The relative contribution of...

Greenstone burial–exhumation cycles at the late Archean transition to plate tectonics
Converging lines of evidence suggest that, during the late Archean, Earth completed its transition from a stagnant-lid to a plate tectonics regime,...

Quartz-bearing rhyolitic melts in the Earth’s mantle
The occurrence of rhyolite melts in the mantle has been predicted by high pressure-high temperature experiments but never observed in nature. Here we...

Origin of life-forming volatile elements in the inner Solar System
Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients to build habitable worlds like Earth, but their origin and...
