When basalt erupts underwater or flows into the sea, contact with the water quenches the surface and the lava forms a distinctive pillowshape, through which the hot lava breaks to form another pillow.This "pillow" texture is very common in underwater basaltic flows and is diagnostic of an underwater eruption environment when found in ancient rocks.

A flood 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 the Deccan Traps of India are often called traps, after the Swedish word trappa (meaning ...
15-12-2013· In the present study, the basaltic, iron-rich, Icelandic lava flow is taken as an analogue for basaltic martian lava flows. One may therefore assume a somewhat similar crystallisation sequence and, thus, similar viscosity evolution during emplacement on Mars although cooling rate, oxygen fugacity, atmospheric pressure and degassing efficiency may temperate direct comparison.
Basalt. Rock Type: igneous (extrusive/volcanic) Composition: feldspar, olivine, pyroxene, amphibole Equivalent to: Gabbro (intrusive/plutonic) Environment: Basalt is solidified lava, like rhyolite.However, it flows much quicker because it is less viscous. The Hawaiian Islands are made of basaltic lava.

Basalt is a major rock type that occurs in virtually every tectonic setting. Basalt is clearly the most common volcanic rock on Earth and basaltic rocks (including gabbro, diabase and their metamorphosed equivalents) are the most common rocks in the crust 2.Basalt is also common on the Moon and other rocky planets of the Solar System.
