Subduction initiation triggered the Caribbean large igneous province [PDF]

open access: yesNature Communications, 2023
Using a large-scale 3D geodynamic model, the authors show how the transfer of subduction zone from the Pacific to the Atlantic triggered the formation of a mantle plume at the origin of the Cretaceous Caribbean Large Igneous province.

Volumetric extrusive rates of silicic supereruptions from the Afro-Arabian large igneous province [PDF]

open access: yesNature Communications, 2021
Quantifying the tempo of large-volume silicic magma generation and eruption is a long-standing but elusive task. Here we show that the three largest sequentially dated eruptions, totaling >4,300 km3, occurred within 48 ± 34 kyr and yield the highest ...

Bilateral geochemical asymmetry in the Karoo large igneous province [PDF]

open access: yesSci Rep, 2018
In the Karoo large igneous province, the geochemical assessment of mantle source variability and structure is hampered by probable crustal contamination overprinting of compositionally diverse flood basalts.

Devonian–Mississippian magmatism related to extensional collapse in Svalbard: implications for radiating dyke swarms [version 1; peer review: 2 approved] [PDF]

open access: yesOpen Research Europe
Background Despite extensive studies of the Mesozoic–Cenozoic magmatic history of Svalbard, little has been done on the Paleozoic magmatism due to fewer available outcrops.

Catastrophic slab loss in southwestern Pangea preserved in the mantle and igneous record

open access: yesNature Communications, 2022
The origin of the Permian-Triassic Choiyoi silicic large igneous province (SLIP) is assessed by linking the igneous record, plate-kinematic reconstructions, and the deep mantle. This study suggests an origin related to a massive slab loss in Pangea.

Large igneous provinces [PDF]

open access: yesEos, Transactions American Geophysical Union, 2007
Catastrophic massive volcanism and contemporaneous environmental change have punctuated Earth history for at least the past 3.5 billion years. Geodynamic and magmatic processes associated with large igneous province (LIP) formation interact with crustal structure and tectonic setting to produce various expressions of LIPs, the most common of which are ...

High temperature methane emissions from Large Igneous Provinces as contributors to late Permian mass extinctions

open access: yesNature Communications, 2022
Methane (CH4) emissions induced by Large Igneous Provinces have the potential to contribute to global environmental changes that triggered mass extinctions in Earth’s history.
