1. As a process such as erosion strips the overlying rocks , granite expands. 2. The core pushes upwards, deforming overlying rock to form a dome. 3. They are under tremendous pressure because of the overlying rock material. 4. The pressure changes deform the overlying rocks , possibly jarring certain faults into action. 5. Since dense materials tend to sink into water, the overlying rock broke under the strain. 6. The Diamond Springs Formation is conformable with the overlying rocks and consists predominantly of serpentinite, tremolite-talc-sills. 7. They were created by uplift-associated pressure release and by the unloading of overlying rock via erosion. 8. Eventually, the Solitario erupted, triggering a massive collapse of overlying rocks and creating a vast caldera. 9. Over the next billion years, the now cooled granite was gradually exposed through erosion of overlying rocks . 10. This process was so pronounced in The Grabens that the overlying rock collapsed into voids left by escaping salt.
