Flood basalt definition
Webbasalt, extrusive igneous (volcanic) rock that is low in silica content, dark in colour, and comparatively rich in iron and magnesium. Some basalts are quite glassy (tachylytes), and many are very fine-grained and compact. 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.

WebA flood basalt is a type of volcanic activity that results in massive amounts of lava flowing out from the Earth’s crust and covering large areas. This occurs when magma rises through fissures, or cracks, in the crust and spreads out over hundreds or thousands of square kilometers. Flood basalts are characterized by their low viscosity and ...
