Tropical forcing of midlatitude terrestrial hydroclimate during the Late Cretaceous

During the ice-free Cretaceous, the tropics have been proposed as key drivers of global climate, yet direct mid- to high-latitude evidence remains absent.

Clinopyroxene In Situ Sr Isotopic Evidence for Crustal Assimilation of Potassic–Ultrapotassic Mafic Magmas in the Southeastern Tibetan Plateau

Potassic–ultrapotassic magmas in continental collision zones have attracted much attention due to their genetic association with magmatic–hydrothermal Cu–Au ore formation and lithospheric mantle evolution.

The mantle source of REE-rich alkaline silicate magmas can be enriched by continent-derived sediment subduction

Alkaline silicate intrusions host large rare-earth-element (REE) resources, yet the precise origin of the mantle enrichment that generates these magmas remains unresolved.

New early cretaceous paleomagnetic results from the Northern Lhasa Terrane and their tectonic implications

The tectonic evolution of central Tibet was shaped by multiple collisions, notably the Cretaceous collision between the Lhasa and Qiangtang terranes and the subsequent India–Asia collision.

Biosphere expansion drives Earth’s secular oxygenation while tectonics modulate oxygen variability revealed by machine learning

The rise of atmospheric oxygen fundamentally transformed Earth’s surface environment and enabled the evolution of complex life.

Quartz-petalite intergrowths in the Yichun pegmatite: Formation from late-stage Li-rich melts and implications for Li mineralization in rare-metal granites

We report a unique quartz-petalite intergrowth that occurs in the core zone of a zoned pegmatite sheet from the Yichun Li-Cs-Ta-Nb mine, China.

Mechanochemical Enhancement of Siderite-To-Magnetite Conversion in Faults

Magnetic phases in fault rocks offer potential “geothermometers” for estimating frictional heating during fault slip.

Paleoelevation variations and exhumation history of the Tibetan Plateau control spatiotemporal distribution of porphyry system deposits

Porphyry deposits, due to their significant size and economic value, have long been a focus of research.

Characterization of Emeralds from Zhen’an County in Shaanxi, China

In 2017, the first emerald deposit in the Qinling Orogenic Belt was found in Zhen’an County, Shaanxi Province, China.

Fine slab structure and mechanism of deep earthquakes beneath central Japan

Deep-focus earthquakes (> 300？km depth) are widely distributed in global subduction zones, but their mechanism is still debated because the fine structure of deep subducting slabs is unclear.
