What is the economic use of igneous rocks?

Igneous rocks have several economic uses due to their durability and aesthetic appeal. They are commonly quarried for construction materials, such as granite and basalt, which are utilized for building, paving, and decorative purposes. Additionally, some igneous rocks contain valuable minerals, such as copper, gold, and lithium, which are extracted for various industrial applications. Overall, their strength and resistance to weathering make them essential in both infrastructure and resource extraction.
