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 such as … 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. Crust formation The extrusion of … 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.

In addition, the Mg# values of these samples range from 72.3 to 73.7, which are primitive magmas ...
WebBased on the lower rates of eruptions in the past few millions of years, we know that flood basalts represent highly anomalous rates of volcanic eruption, because they appear to upset Earth’s hydrospheric system.
