Tholeiitic Basalt

Basalts are a group of fine-grained extrusive igneous rocks that have a relatively low silica content, but otherwise vary significantly in composition and appearance. They may, for instance, be compact, smooth, and glassy or porphyritic and can exhibit a wide range of colors, such as dark green, reddish brown, gray, or black.
