Question

Quizplus · Accepted Answer

Plutonic rocks are formed by the solidification of magma deep below the Earth's surface, typically at temperatures between 650 and 1200 degrees Celsius. As magma cools, minerals in it crystallize and form rocks. Felsic rocks are rich in minerals such as quartz and feldspar and have a lower density than mafic rocks, which are rich in minerals such as olivine and pyroxene. Plutons are typically associated with felsic rocks, such as granite and diorite, which are commonly found in mountain ranges and other areas of significant geologic activity. While plutons can also be composed of intermediate or mafic rocks, they are less common than felsic plutonic rocks.
