| 説明 | Sandstone in the Silurian of Tennessee, USA. (geology hammer for scale)The Clinch Formation (a.k.a. Tuscarora Quartzite, Clinch Sandstone, Tuscarora Sandstone; Clinch Quartzite, Tuscarora Formation) generally consists of hard, well-cemented, quartzose sandstones and some quartz-pebble conglomerates. Commonly seen sedimentary features include cross-bedding and burrows. The quartz grains in the Clinch appear to have been recycled, probably several times during the Precambrian and Early Paleozoic. These sediments were deposited near the end of the Taconic Orogeny. The beds themselves were structurally tilted during the Allegheny Orogeny, in the Late Paleozoic.
