mafic rocks

Mafic rocks are a type of igneous rock that contains a high amount of magnesium and iron, giving them a darker color. They form from magma that cools quickly on the Earth's surface or slowly underground. Common examples include basalt and gabbro. These rocks are rich in minerals like olivine and pyroxene, contributing to their dense, durable nature. Mafic rocks are significant because they make up much of the Earth's oceanic crust and are important in understanding geological processes like volcanic activity and crust formation.
