WebHornfels— A metamorphic rock containing micas, quartz and garnets and that is formed from clay-rich rocks. Kilobar— A unit of measure used to express the high pressures found within Earth ’ s interior. It is referenced to air pressure, the force exerted by the weight of the atmosphere at Earth ’ s surface, which equals one bar.
