TitleEpidote vein in granite, near Mt. Whitney, Sierra Nevada Mountains
DescriptionThis rock split open along a vein of epidote. The epidote formed from feldspar interacting with water that flowed along a fracture in the rock. This sort of secondary mineralization is quite common in feldspar-containing rocks, although usually not to the extent shown here.
