The formation of Hongge Fe-Ti-V oxide deposit hosted in layered intrusion, Emeishan Large Igneous Province, Southwest China [PDF]

open access: yes, 2023
The origin of Fe-Ti-V oxide ore layers, especially the monomineralic Fe-Ti-V oxide ores, in layered intrusions remains controversial. To reveal the Fe-Ti-V oxide mineralization processes, we had chosen the giant Hongge Fe-Ti-V oxide deposit in Emeishan ...

An abrupt extinction in the Middle Permian (Capitanian) of the Boreal Realm (Spitsbergen) and its link to anoxia and acidification [PDF]

open access: yes, 2015
The controversial Capitanian (Middle Permian, 262 Ma) extinction event is only known from equatorial latitudes, and consequently its global extent is poorly resolved.

Anatomy of the Emeishan Mantle Plume Head: Insights From New Geochronologic, Geochemical, and Geologic Data

open access: yesGeochemistry, Geophysics, Geosystems
The link between mantle plumes and the formation of large igneous provinces (LIPs) is well established although the anatomy of these remains equivocal. Recent experimental studies and geophysical data suggest that the mantle plume head is more likely to ...

Contribution of the Rheologically Weak Lower Crust to Contemporary Crustal Motions in the Southeastern Tibetan Plateau, China

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The southeastern Tibetan Plateau (SETP) plays a pivotal role in accommodating intra‐continental deformation driven by the ongoing India‐Eurasia convergence. However, its contemporary surface vertical motions and the underlying geodynamic processes remain highly debated.

Heavy boron isotopes in plume-derived magmas trace recycled water in deep-mantle reservoir

open access: yesCommunications Earth & Environment
The debate on the origin of water in the Earth’s interior focuses on whether it originates from internal primordial sources or externally from the Earth’s surface via subduction-related processes. Here we report boron isotope data for Middle/Late Permian

Evolution of the Paleo–Tethyan Ocean between the South China and Indochina Blocks: Insights from the Babu Ophiolite in Southwestern China [PDF]

open access: yesLithosphere
The Paleo–Tethyan Ocean in Southeast (SE) Asia is generally considered to be primarily represented by the Jinshajiang–Ailaoshan suture between the South China and Indochina Blocks.

Flood basalt-related Fe–Ti oxide deposits in the Emeishan large igneous province, SW China

open access: yesLithos, 2010
In the Panzhihua–Xichang region (Sichuan Province, SW China), there are a number of world-class magmatic Fe–Ti oxide deposits. They are hosted as conformable masses in lower parts of layered mafic–ultramafic intrusions that are part of the end-Guadalupian (∼ 260 Ma) Emeishan large igneous province.

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

open access: yesJournal 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 ...
