Briefly explain how exfoliation domes form. What will be an ideal response?
Exfoliation domes form from pressure release and are typically found in granite. Igneous intrusive
rocks form at tremendous depth and pressure. When they are uplifted, the pressure is released, and the
rock can expand. It does so along fractures called sheet joints that more or less parallel the existing
rock surface. Slabs of rock bounded by sheet joints slide off the parent rock, leaving behind a dome.
