Basalt Rocks. Basalt is an extrusive igneous rock that is very dark in color. It is the most common type of rock in the Earth's crust and it makes up most of the ocean floor. It is made of many dark colored minerals such as pyroxene and olivine.Basalt also contains some light colored minerals such as feldspar and quartz, but the amounts are small.t is the most common type of rock in the Earth's crust and it makes up most of the ocean floor.

As a result, they are very dark in color, and usually appear as shades of black and black-green. Occasionally, some red or orange colors can appear in basalts and are due to that particular basalt containing rusting iron compounds. Basalt is an igneous rock that forms from the cooling and crystallization of magma. And usually, magma is formed from the melting of dark colored peridotite and pyroxene-rich rocks. There are some lighter colored basalts found, which form when a basalt magma contains a higher than normal amount of calcium or sodium minerals. Formation of Basalt.
