A large igneous province (LIP) is an extremely large accumulation of igneous rocks, including intrusive (sills, dikes) and extrusive (lava flows, tephra deposits), arising when magma travels through the crust towards the surface.

Large igneous provinces (LIPs) are massive crustal emplacements of predominantly iron- and magnesium-rich (mafic) rock that form by processes other than normal seafloor spreading; they are the dominant form of near-surface magmatism on the terrestrial planets and moons of …

2021年11月23日 · 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...

Large Igneous Provinces of the Circum-Pacific region (in red) emplaced since 250 Ma. From cover of Mahoney, J.J. and M.F. Coffin (eds.), Large Igneous Provinces: Continental, oceanic, and planetary flood volcanism.

2013年1月1日 · Large igneous provinces are home to the largest known basaltic and silicic eruptions (or supereruptions) on Earth, with eruption magnitudes up to ∼10,000 km 3 or magnitude 9.4 now recognized; many examples of both basaltic and rhyolitic supereruptions are now known that far exceed the erupted volume of the ∼5000 km 3 Fish Canyon Tuff, which ...

Among the terrestrial planets and moons of our solar system, however, global plate tectonics may well be unique to Earth. Even on Earth, current plate tectonic theory does not predict major crustal growth events termed large igneous provinces, LIPs (Figure 3.3.3.1).

Large Igneous Provinces (LIPs) are intraplate magmatic events, involving volumes of mainly mafic magma upwards of 100 000 km3, and often above 1 million km3.

Richard Ernst studies the huge volcanic events called Large Igneous Provinces (LIPs) — their structure, distribution, and origin as well as their connection with mineral, metal, and hydrocarbon resources; supercontinent breakup; and mass extinctions.

The key aspect of large igneous provinces (LIPs) is that they represent anomalously high magmatic fluxes. The magma is usually basaltic, but may be rhyolitic. They are large in area, covering many thousands if not millions of square kilometres, and they testify to unusual geological processes, involving large amounts of thermal energy. Where this

Large igneous provinces record major outpourings of igneous rocks, both on the continents and in ocean basins. Their origin is still vigorously disputed, with models invoking mantle plumes, thermal effects of the lithosphere, and meteorite impacts.
