Escalation of caldera unrest indicated by increasing emission of isotopically light sulfur
Calderas are depressions formed by some of the largest volcanic eruptions. Their long-lived inter-eruptive periods are occasionally interrupted by …
Rapid rise of early ocean pH under elevated weathering rates
Ocean pH is a fundamental property regulating various aspects of Earth system evolution. However, early ocean pH remains controversial, with estima…
Geochemistry of lithospheric aqueous fluids modified by nanoconfinement
Water is a principal component of Earth’s fluids, and its interaction with rocks governs lithospheric geochemical and geodynamic processes. Water…
Evidence for pre-Noachian granitic rocks on Mars from quartz in meteorite NWA 7533
The surface of Mars has long been seen as a basaltic, monotonous world, but observations in the past decade have revealed more petrological diversi…
Persistence of davemaoite at lower-mantle conditions
The lower mantle occupies over half of Earth’s volume, and accordingly, its mineralogy is crucial in determining the structure and dynamics of Ea…
Genesis and timing of KREEP-free lunar Mg-suite magmatism indicated by the first norite meteorite Arguin 002
There is ongoing debate about whether lunar magnesian suite (Mg-suite) magmatism was a global, nearly synchronous event with a genetic link to pota…
Thermochronological markers reveal Late Cretaceous strike-slip faulting in the Yangtze Block, South China
Detecting strike-slip tectonics using thermochronology is challenging because the complex relative motion between fault blocks often does not subst…
