Dark colored igneous rocks are high in iron and other heavier elements: ma-fic, magnesium-iron. Light color igneous rocks are high in aluminum and potassium. .ou need to understand one of the fundamental differences between mafic and felsic rocks. Mafic rocks contain larger amounts of Mg and Fe than felsic rocks. The atomic weights of Mg and Fe are higher than Al, Si, and O, therefore they tend to be heavier. Very simple concept.
Background: The term igneous comes from the Latin ignis, meaning fire. Igneous is used to describe rocks that crystallize out of hot molten material in the Earth called magma. When magma pushes up through Earth's crust to the surface, it is called lava.Both magma and lava cool and harden to form igneous rocks.ackground: The term igneous comes from the Latin ignis, meaning fire.
