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.
IGNEOUS ROCKS are formed from the solidification of molten rock. Most of the Earth is composed of igneous rock. There are 2 major types of igneous rocks; intrusive igneous rocks, and extrusive igneous rocks.INTRUSIVE IGNEOUS ROCKS solidify beneath the Earth's surface.Because the magma cools over a relatively long period of time, Intrusive igneous rocks tend to have large mineral crystals that give the rock a rough granular texture.NTRUSIVE IGNEOUS ROCKS solidify beneath the Earth's surface.
