Abstract Zircon double dating (ZDD) of comendite lava reveals an eruption age of 7.0 ± 0.9 ka for the Qixiangzhan eruption (QXZ), Changbaishan-Tianchi volcano, China/DPRK. This age is supported by new 40Ar/39Ar sanidine experiments and a previous ag

Abstract The genesis and timing of formation of the giant Bayan Obo deposit, the world's largest rare earth element (REE) deposit in the western part of the late Paleozoic northern North China continental arc (NCA), are highly controversial due to co

The ultimate driver of ultraslow spreading ridges is unknown. Here the authors use spreading rates derived directly from isotopic ages of seafloor samples to link magmatic and amagmatic segments with thermochemical variations in the upper mantle.

Post-caldera eruptions at Toba Caldera, Sumatra, following the supereruption 74,000 years ago, sampled cooler margins of the warm magma reservoir and imply its heterogeneity, according to thermochronology analyses coupled with Bayesian statistics.

Low seismic velocity anomalies reveal a complex scenario of plume upwellings from a deep thermo-chemical anomaly (superplume) in the mantle below the East African Rift, however, geophysical observations alone are insufficient to identify the extent o

Miocene rhyolitic volcanism of eastern Oregon, USA, can be divided into two main episodes. Mantle plume upwelling is thought to have generated Columbia River Basalt Group (CRBG) lavas and coeval >16.5−15 Ma silicic volcanism trending north−south
