Most of the rocks in Great Smoky Mountains National Park are sedimentary and were formed by accumulations of clay, silt, sand, gravel, and minor amounts of calcium carbonate in flat-lying layers. Mountains can be explained as landforms that rise well above the surrounding land for a limited area in the form of a peak. Finally the Blue Mountains were pushed up and the coastal sediments sagged, creating the eastern escarpment of the Blue Mountains. Volcanic mountains form when molten rock from deep inside the Earth erupts through the crust and piles up on itself. |The Jenolan Caves which have formed in limestone rock are evidence that this area was once a shallow sea. In medieval times, before the advanc… Blue Mountains National Park, a 1,035-square-mile (2,680-square-km) nature reserve centred on the Grose River valley, lies within the region. The Glass House Mountains in Queensland were also partly caused by volcanic hot spots. The Ainur who subsequently entered the physical world of Middle-earth were the Valar ("powers"), though that term came to refer primarily to the mightiest among them.

The oldest rocks in the Blue Mountains comprising the region's basement, are faulted, folded, intruded and lightly metamorphosed rocks formed mainly from marine sediments deposited 470-330 million years ago (m.y.) Colliding chunks of continental crust created mountains rising high on the surface, and pushing other rocks deep enough to melt and blend.
