Arch Rock
The Formation of Granite This type of rock is called White Tank Granite. It is an igneous rock which formed when hot magma or liquid rock was pushed up from deep within the Earth and forced into the overlying rock in a process known as intrusion. It then cooled and hardened and later became exposed as the rock we see today. Geologists believe that the White Tank Granite was intruded into the overlying rock about 135-155 million years ago. < Previous --- Next > |
