Carbon Black Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene. It is the most common rock type found in oceanic crust and is an important component of the Earth’s continental crust. Basalt is formed through the rapid cooling and solidification of magma at Earth’s surface, resulting in the formation of lava flows and volcanic rocks. It’s used for pavers, copings, pier caps, walls, risers, curbs, cobbles and many other applications. Basalt is available in a variety of finishes - flamed, honed, lappato, leather, sand and shot blasted to meet a variety of aesthetic and functional needs. It has great strength and durability.
