Encyclopedia > Basaltic flood

A basaltic flood is a giant volcanic eruption that coats large stretches of land with basalt lava. Basaltic floods have occurred on continental scales in prehistory, creating great plateaux and mountain ranges that have survived many millions of years after the events that created them.


The two largest basaltic flood events in historic time have been at Eldgjá and Lakagigar, both in Iceland.

Flood basalt - Wikipedia, the free encyclopedia (281 words)
A flood basalt is a giant volcanic eruption that coats large stretches of land or the ocean floor with basalt lava.
One explanation for flood basalts is that they are caused by the combination of continental rifting and its associated decompression melting in conjunction with a mantle plume also undergoing decompression melting producing vast quantities of a basaltic magma.
Flood basalts have erupted at random intervals throughout history and are clear evidence that the Earth undergoes periods of enhanced activity rather than being in a uniform steady state.
