Cliff-forming quartzite, the principle part of the Eureka, is composed of more than 99 percent quartz, which includes both the sand grains and the cement that binds them. [6] The quartz cement accounts for its outstanding hardness and resistance to erosion. Minor constituents are grains of zircon and tourmaline and a trace of feldspar. [6]
They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distortion. Metamorphic rock can be formed locally when rock is heated by the intrusion of hot molten rock called magma from the Earth's interior. The study of metamorphic rocks (now exposed at the Earth's surface following ...
