Basalt
Basalt is also a common rock on the surface of Mars.
Basalt is formed on Earth's Moon, Mars, Venus, and even on the asteroid Vesta.
Basalt is the most typical rock of large igneous provinces.
Basalt has high liquidus and solidus tempertures about above 1200 C (liquidus) and near or below 1000 C (solidus).
The shape and tecture of basalt depends on where and how it gets erupted.
This rock is a common extrusive volcanic rock.
This rock is usually grey to black and fine-grained from the rapid cooling of the lava at the surface of a planet.
Ancient Precambrian basalts are usually found in fold and thrust belts, and are often heavily metamorphosed.
