- What Kind Of Rock Is Basalt
Basalt is a lava rock with low silica content. Both gabbro and basalt cool from mafic magma. Gabbro is an intrusive rock so it cooled more slowly and has larger crystals. Basalt is an extrusive rock so it cooled more quickly and has smaller crystals.

This is rock that is formed on the surface of the earth. In contact with air or seawater, molten rock cools rapidly and either quenches to a glass (like obsidian) or forms small crystals (basalt). Volcanic rocks are usually finely grained or glassy in structure. Basalt is an extrusive rock, finely grained due to its rapid cooling.

Why basalt? Basalt is a volcanic rock, such as that which makes up Iceland or Hawaii. Basalt is mafic, meaning low amounts of silica and lots of divalent metal cations (meaning with a 2+ charge) such as Ca 2+, Mg 2+ and Fe 2+. Calcium and magnesium are two key components of the long-term carbon cycle because they are required for carbon ...

Greenstone. In Minnesota, greenstone is somewhat younger than the gneiss. Greenstone is a weakly metamorphosed basalt that is greenish to gray. This type of rock formed about 2.7 billion years ago, when the area that is now northern Minnesota was part of a volcanic island arc, much like the islands of Japan are today.
