Mineral terraces. Mineral terraces at Mammoth Hot Springs,Yellowstone National Park,Wyoming,USA. The terraces form at the outflow of geothermal springs. The water,heated under pressure deep underground,dissolves large amounts of minerals from the surrounding rocks and then deposits them at the surface as it cools. The white material on the terraces in the foreground is the mineral travertine (calcium carbonate) | |
