Re-evaluating plume-induced uplift in the Emeishan large igneous province

Nature Geoscience, 2008
Numerical and fluid dynamic modelling predicts that mantle plumes should generate a broad domal uplift (>1,000 km wide, 500 to ⩾1,000 m high) preceding volcanism in large igneous provinces. The Emeishan large igneous province (southwest China) has been offered as the best example of plume-induced uplift, where kilometre-scale pre- and syn-volcanic ...

Multilocus Phylogeny of Asiatic Striped Squirrels (Sciuridae, Tamiops) Reveals Their Evolutionary Relationships and Species Limits

Ecology and Evolution, Volume 16, Issue 2, February 2026.
The genus Tamiops has long been underestimated in terms of species diversity due to reliance on seasonal fur coloration. This study integrates mitochondrial whole‐genome and nuclear gene data to identify seven monophyletic lineages, elevating T. maritimus hainanus to independent species status.

Origin of two types of rhyolites in the Tarim Large Igneous Province: Consequences of incubation and melting of a mantle plume [PDF]

, 2014
The Early Permian Tarim Large Igneous Province (LIP) in northwestern China contains a large area of silicic volcanics (similar to 48,000 km(2)) which are spatially and temporally associated with mafic-ultramafic rocks. In order to understand the behavior

Numerical Modeling of Purely Active (Plume‐Produced) Continental Rifting and Break‐Up

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract In contrast to the traditional mechanism of passive continental rifting (driven by far‐field tectonic forces), the active rifting‐to‐break‐up processes (caused by rising mantle plumes) are still poorly understood. However, most episodes of fragmentation of the last supercontinent Pangea were relatively shortly preceded (within ∼10 Myr) by the ...

Humps in κ‐T Curves: Evidence for the Stable Single‐Domain to Superparamagnetic Transition in Magnetite

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Thermomagnetic susceptibility (κ‐T) curves are used widely for magneto‐mineralogical analysis. Humps in heating curves below the Curie temperature of magnetite are observed frequently. We present κ‐T curves with hump features in magnetite‐bearing flood basalt samples.

Viscosity of Dry and Hydrous Diopside Melts at High Pressures: Implications for Upper Mantle Magma Dynamics

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Viscosity of silicate melts governs magma transport and influences mantle dynamics, yet effects of pressure and water on melt viscosity remain poorly understood. Here, we report in situ falling‐sphere viscosity measurements on diopside (Di) melts with 0–3 wt.% H2O along the liquidus up to 7 GPa and 2103 K using synchrotron X‐ray radiography ...
