WebFlood basalts in the oceans are known as oceanic plateaus, and include the Ontong Java plateau of the western Pacific Ocean and the Kerguelen Plateau of the Indian Ocean. The narrow vertical pipe, or conduit, postulated to connect the plume head to the core-mantle boundary, is viewed as providing a continuous supply of magma to a fixed location ...

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 hotspot reaching the surface of the earth via a mantle plume. Flood basalt provinces … See more 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, … 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 explain the similar compositions and tectonic settings of flood basalts erupted … 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 … 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 WebMar 21, 2024 · Flood basalt eruptions are extended periods of near-continuous but low-intensity volcanism punctuated by large explosive events, somewhat resembling the lava flows from Kīlauea Volcano’s Lower ...
