Summary
[edit]DescriptionSandstone (Henley Member, Borden Formation, Lower Mississippian; AA Highway roadcut, Lewis County, Kentucky, USA) (34625252765).jpg |
Sandstone from the Mississippian of Kentucky, USA. This fine-grained sandstone sample is from an interbed in a shale succession in Kentucky's Borden Formation. The Borden is an ancient delta deposit. The sediments were derived from erosion of mountains to the east, in what is now the Appalachians. The Appalachians of eastern America formed as a result of three separate mountain-building events during the Paleozoic: 1) Taconic Orogeny (Ordovician to Silurian); 2) Acadian Orogeny (Silurian to Devonian); and 3) Allegheny Orogeny (Carboniferous). Borden Formation sediments formed as the ancient Acadian Mountains eroded. Considerable amounts of sand, silt, and mud were washed down ancient rivers from the east and northeast and were deposited in deltaic environments - this was the Borden Delta.
