![]() ![]() Now, let’s understand the basalt formation at various locations: Gas cavities are absent in the basalt lows and these floors are generally quite thick and extensive. For example, the lunar maria are plains of flood basaltic lava flow and basalt is a common rock existing on the surface of Mars.īasalt rocks are usually formed when the volcanic basaltic Lava rapidly cools from the deep interior of the earth's crust equivalent to plutonic gabbro-norite magma and gets exposed to the Earth surface. Basalt is also a crucial volcanic rock type on other planetary bodies in the Solar System. We must note that more than 90% of all volcanic rock on Earth is basalt, and the eruption/bursting of basalt lava is seen by geologists at around twenty volcanoes every year. In this article, we will understand what basalt is, the use of basalt, basalt type, and more about this in detail.īasalt is an igneous rock that is formed from the quick cooling of lava rich in magnesium and iron when exposed at or very near the surface of a terrestrial planet or the moon. From these places, we get a clear idea that understanding basalt use is really important for us. ![]() We find its applications in textile industries, fire protection. Maria, the dark plains on the Moon and also volcanoes of Mars and Venus are known to be possibly made up of basalt.Ī basalt dark in colour can be called the dark basalt. ![]() Basalt rocks have also built up huge plateaus on the surface of the land. ![]() When erupted by volcanoes in ocean basins, it can lead to the formation of volcanic Islands. A large part of the ocean floors is made from basalt rocks. The specimens of these rocks are mostly fine-grained, glassy and compact. The texture of basalt rocks is coarsely porous as those holes are left by gas bubbles. Basalt rock is mainly composed of pyroxene, olivine, and plagioclase and is the most common rock on the earth's surface. Basalt is an extrusive igneous or volcanic rock that has a low silica content, dark in colour, and is very rich in iron and magnesium. ![]()
