What rock is found 10 kilometers beneath the earthhs surface?

Approximately 10 kilometers beneath the Earth's surface, you would typically find rocks that are part of the upper mantle or lower crust, primarily composed of metamorphic and igneous rocks. Common examples include granite and gneiss in the continental crust, and basalt in oceanic crust. The temperature and pressure at this depth create conditions that can lead to significant metamorphism of these rocks.
