Flood basalts are the most voluminous of all extrusive igneous rocks, forming enormous deposits of basaltic rock found throughout the geologic record. They are a highly distinctive form of intraplate volcanism, set apart from all other forms of volcanism by the huge volumes of lava erupted in geologically … See more A flood basalt (or plateau basalt ) is the result of a giant volcanic eruption or series of eruptions that covers large stretches of land or the ocean floor with basalt lava. Many flood basalts have been attributed to the onset of a See more Theories of the formation of flood basalts must explain how such vast amounts of magma could be generated and erupted as lava in such short intervals of time. They must also … See more Flood basalts contribute significantly to the growth of continental crust. They are also catastrophic events, which likely contributed to many mass extinctions in the geologic record. See more The interlocking crystals of flood basalts, which are oriented at random, make trap rock the most durable construction aggregate of all rock types. See more Large Igneous Provinces (LIPs) were originally defined as voluminous outpourings, predominantly of basalt, over geologically very short durations. This definition did not specify minimum size, duration, petrogenesis, or setting. A new attempt to refine … See more Representative continental flood basalts and oceanic plateaus, arranged by chronological order, together forming a listing of large igneous provinces: Elsewhere in the Solar System Flood basalts are the dominant form of magmatism on the … See more • Geology portal • Supervolcano – Volcano that has erupted 1000 cubic km of lava in a single eruption • Volcanic plateau – Plateau produced by volcanic activity See more WebFlood basalt definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation.

WebFlood basalts are one type of large igneous province (LIP) that characterise the Earth's surface and have been formed at various times in the geological past - some in a … WebLIPs consist of volcanic packages (flood basalts) and a plumbing system of regional dyke swarms (linear, radiating, and a newly identified circumferential type), sill complexes, layered mafic–ultramafic (M–UM) intrusions, and crustal magmatic underplates ( Ernst et al., 2024 ). WebDuring late Miocene and early Pliocene times, a flood basalt engulfed about 63,000 square miles (160,000 km 2) of the Pacific Northwest, forming a large igneous province. [2] Over a period of perhaps 10 to 15 million years, lava flow after lava flow poured out, ultimately accumulating to a thickness of more than 6,000 feet (1.8 km). [2] csgo failed to create d3d
