Basalt: Rock, Lava & Formation Traits | Vaia
The Formation and Characteristics of Basalt Rock. Basalt forms mainly through a rapid cooling effect on the large amounts of lava flow. This rapid cooling and solidification prevent large crystal formations, making basalt fine-grained or aphanitic. Basalt exhibits a range of shades from grey to black, depending upon its mineral and iron content.

This relatively low silica content classifies basalt as a mafic rock, which is less viscous compared to felsic rocks like granite. Alumina (Al₂O₃) : Basalt contains about 13% to 18% alumina. This is primarily due to the presence of plagioclase feldspar, a key mineral in basalt.
Basalt Rock
Basalt rock is mainly composed of pyroxene, olivine, and plagioclase and is the most common rock on the earth's surface. The texture of basalt rocks is coarsely porous as those holes are left by gas bubbles. The specimens of these rocks are mostly fine-grained, glassy and compact. A large part of the ocean floors is made from basalt rocks.

What Is Basalt Rock? Basalt is an igneous rock formed from flowing lava that's cooled when it reaches the earth's surface. Much like Scoria, it is an extrusive stone composed of minerals often found in magma like magnesium and iron.. Basalt can also form platonically within the earth's crust if magma reaches a cooler temperature without an actual volcanic eruption.
