Granite is a hard, plutonic igneous rock that consists of coarse-grained minerals such as quartz (gray to white), feldspar (white or pink), and mica (black). It forms when underground magma cools slowly, allowing the different minerals to crystallize. Granite is commonly used as a building material.
Jordan’s oldest rocks are mostly granite. They lie under mountains like Wadi Rum’s, but they are exposed in southern Jordan, south and north of Aqaba.
