Question: 1 / 400
Which mineral is most commonly found in granite?
Calcite
Quartz
Granite is an igneous rock that is primarily composed of several minerals, with quartz being the most abundant. Quartz is a hard, durable mineral that gives granite much of its strength and resistance. The characteristic speckled appearance of granite comes from the variety of colors and sizes of the mineral grains, with quartz often being prominent. In addition to quartz, granite typically contains feldspar and mica, which contribute to its overall composition. Understanding the makeup of granite is essential for topics such as geology and construction, where the properties of rocks and their components are important. Other minerals listed, such as calcite, iron, and slate, do not primarily compose granite, making quartz the most accurate answer.
