Carbonate-capped seamount subduction accelerates CO2-rich arc magma ascent [PDF]
Nature CommunicationsSubduction transports carbon into Earth’s interior, yet how subducted carbon influences arc magma ascent dynamics remains unclear. Here we combine volatile compositions of olivine-hosted melt inclusions with olivine diffusion chronometry at Pagan volcano

Geophysical Monograph Series, Page 435-447., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Widespread phosphorous excess in olivine, rapid crystal growth, and implications for magma dynamics
Volcanica, 2022 Trace element zoning is often used to unravel the crystallization history of phenocrysts in magmatic systems, but interpretation requires quantifying the relative importance of equilibrium versus disequilibrium.

A snapshot of the transition from monogenetic volcanoes to composite volcanoes: case study on the Wulanhada Volcanic Field (northern China) [PDF]
European Journal of Mineralogy, 2022 The transition processes from monogenetic volcanoes to composite volcanoes are poorly understood. The Late Pleistocene to Holocene intraplate monogenetic Wulanhada Volcanic Field (WVF) in northern China provides a snapshot of such a transition.

Transient Creep in Subduction Zones by Long‐Range Dislocation Interactions in Olivine
Journal of Geophysical Research: Solid Earth, 2022 AbstractLarge earthquakes transfer stress from the shallow lithosphere to the underlying viscoelastic lower crust and upper mantle, inducing transient creep during the postseismic interval. Recent experiments on olivine have provided a new rheological model for this transient creep based on the accumulation and release of back stresses among ...

Frontiers in Earth Science, 2019 Our current knowledge of the genesis, ascent, storage, and eruption of mafic magmas is intimately linked with olivine, its primary crystal cargo. Recent claims that phenocryst-size crystals can grow rapidly and non-concentrically are challenging our ...

Geothermobarometry and nature of intermediate lavas from the south of Damavand volcano [PDF]
پترولوژی, 2023 Damavand stratovolcano is in Alborz Magmatic Belt (AMB), in the north of Iran, and the Iranian plateau. This large dormant volcano was constructed with a composite large cone (more than 400 km2). Damavand is known as the highest mountain (elevation ~5671
