small scale rock gold process

Causes of Rock Deformation • Stress pressure placed on rocks • Strain deformation of the rock • Strength rock resistance to deformation • Brittle deformation the rocks break or fracture. Occurs at low temperatures and low pressures. • Ductile deformation the rocks bend or flow. Occurs at higher temperature and pressures.
