The Emeishan large igneous province: A synthesis

Geoscience Frontiers, 2014
AbstractThe late Permian Emeishan large igneous province (ELIP) covers ∼0.3 × 106 km2 of the western margin of the Yangtze Block and Tibetan Plateau with displaced, correlative units in northern Vietnam (Song Da zone). The ELIP is of particular interest because it contains numerous world-class base metal deposits and is contemporaneous with the late ...

Synchronous Emplacement of the Anorthosite Xenolith‐Bearing Beaver River Diabase and One of the Largest Lava Flows on Earth

Geochemistry, Geophysics, Geosystems, 2021
New geochronologic and paleomagnetic data from the North American Midcontinent Rift (MCR) reveal the synchronous emplacement of the Beaver River diabase, the anorthosite xenoliths within it, and the Greenstone Flow—one of the largest lava flows on Earth.

Geophysical and Geochemical Evidence for a New Mafic Magmatic Province Within the Northwest Shelf of Australia

Geochemistry, Geophysics, Geosystems, 2022
The formation of mafic magmatic provinces are significant geological events that can drive mass extinctions and continental rifting and can influence basin evolution, petroleum prospectivity and mineralization.

THE LIFE CYCLE OF LARGE IGNEOUS PROVINCES

Geological Society of America Abstracts with Programs, 2021
Extremely voluminous magmatic systems known as large igneous provinces (LIPs) punctuate Earth’s history, and the gases they release plausibly link large-scale geodynamic and magmatic processes with major climate shifts in Earth’s geological record. However, quantifying the relationships between magmatism, gas release and environmental changes remains ...

A Mesoarchean Large Igneous Province on the Eastern Kaapvaal Craton (Southern Africa) Confirmed by Metavolcanic Rocks from Kubuta, Eswatini

Lithosphere, 2022
Mesoarchean magmatism is widespread on the eastern margin of the Kaapvaal Craton, but its origin is still poorly understood, mainly because geochemical data is rare.

Evidence of explosive hydromagmatic eruptions during the emplacement of the North Atlantic Igneous Province

Volcanica, 2020
Early Eocene sediments in northwest Denmark contain over 180 well-preserved volcanic ash layers, likely sourced from the North Atlantic Igneous Province (NAIP) between 56.0 and 54.6 Ma.

Lithostratigraphy and volcanic facies architecture of the Paraná Continental Magmatic Province in its NE edge with the Alto Paranaíba Arch, Minas Gerais State, Brazil

Brazilian Journal of Geology, 2020
In the NE edge of the Paraná Continental Magmatic Province (PCMP), compound pahoehoe, simple pahoehoe, rubbly flows, pillow lava, and simple pahoehoe/pyroclastic flows linked to ring structures with lithofacies associations have been identified.

Age and Geochemistry of High Arctic Large Igneous Province Tholeiitic Magmatism in NW Axel Heiberg Island, Canada

Geochemistry, Geophysics, Geosystems, 2023
The Cretaceous High Arctic Large Igneous Province (HALIP) in Canada involved extrusion of continental flood basalts (CFBs) at 130–120 Ma and 100‐95 Ma and emplacement of an extensive sill and dike network that intersected the Carboniferous to Paleogene ...

Mercury Anomalies Link to Extensive Volcanism Across the Late Devonian Frasnian–Famennian Boundary in South China

Frontiers in Earth Science, 2021
The Late Devonian Frasnian–Famennian (F–F) mass extinction has been long-time debated by non-volcanic causes, extra-terrestrial impacts, and large igneous province (LIP) eruptions.

Large igneous provinces and mass extinctions: an update [PDF]

, 2014
The temporal link between mass extinctions and large igneous provinces is well known. Here, we examine this link by focusing on the potential climatic effects of large igneous province eruptions during several extinction crises that show the best ...
