Basalt and Suevite
Definition
Definition
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Formation
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Basalt and Suevite Properties
Know all about Basalt and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Basalt belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Basalt is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Suevite is Earthy. Basalt appears Dull and Soft and Suevite appears Banded. The luster of Basalt is not available while that of Suevite is earthy. Basalt is available in black, brown, light to dark grey colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Basalt are an oil and gas reservoir, commemorative tablets, creating artwork, used in aquariums and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
