Basaltic magma is a type of molten rock that forms from the partial melting of the Earth's mantle. It is rich in iron and magnesium, which gives it a darker color and a lower viscosity compared to other types of magma. This makes basaltic magma flow more easily, allowing it to travel long distances before solidifying. When basaltic magma erupts, it typically results in shield volcanoes or lava flows. These eruptions are often less explosive than those of more viscous magmas, leading to the formation of broad, gently sloping volcanic structures. The solidified rock is known as basalt, which is commonly found in oceanic crust and volcanic islands.
