The Stockdale Shales is a geologic formation in England. It preserves fossils dating back to the Silurian period.
The shales were named by W. Talbot Aveline from the beck and hamlet of that name in Longsleddale. [1]
Longsleddale is a valley and civil parish in the South Lakeland district of the English county of Cumbria. It includes the hamlet of Sadgill. The parish has a population of 73. As the population taken at the 2011 Census was less than 100, details are maintained in the civil parish of Whitwell and Selside.
The Aymestry Limestone is a fossiliferous limestone of Gorstian age deposited in a warm shallow sea near the eastern margin of the Iapetus Ocean. It occurs in England in the Ludlow Group, between the Upper and Lower Ludlow Shales. It derives its name from Aymestrey (sic), Herefordshire, where it may be seen on both sides of the River Lugg. It is well developed in the neighbourhood of Ludlow and occupies a similar position in the Ludlow shales at Woolhope, the Abberley Hills, May Hill and the Malvern Hills.
William Talbot Aveline (1822–1903) was a British geologist and archaeologist.
The Hinton Formation is a geologic formation in West Virginia. It preserves fossils dating back to the Carboniferous period. It is mainly made up of limestone, sandstone, and shale.
The Rochester Shale is a geologic formation exposed in New York and West Virginia. It preserves fossils dating back to the Silurian period.
The Ohio Shale is a geologic formation in Ohio. It preserves fossils dating back to the Devonian period.
The Cuyahoga Formation is a geologic formation in Ohio. The age of the formation is difficult to determine, because of a lack of diagnostic fossils. Roughly, the formation dates from the Late Kinderhookian to the Middle Osagean. Eight members are recognized, among them the Orangeville Shale, Sharpsville Sandstone, and Meadville Shale.
The Sonyea Group is a geologic group in the northern part of the Appalachian Basin. It preserves fossils dating back to the Devonian period.
The Java Formation is a geologic formation in Kentucky, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia. It preserves fossils dating back to the Devonian period. The formation comprises the Pipe Creek Shale, Wiscoy Sandstone Member in New York, and Hanover Shale Member except in Tennessee.
The Kinzers Formation is a geologic formation in Pennsylvania. It preserves fossils dating back to the Cambrian Period.
The Genesee Group is a geologic formation in Pennsylvania. It preserves fossils dating back to the Devonian period.
The Cashaqua Shale is a geologic formation in New York. It preserves fossils dating back to the Devonian period.
The Benton Shale is a geologic formation in Montana, Wyoming, North Dakota, South Dakota, Colorado, Kansas, and Nebraska. It preserves fossils dating to the Cretaceous Period. The term Benton Limestone has also been used to refer to the chalky portions of the strata, especially the upper beds of the strata presently classified as Greenhorn Limestone. The Benton classification is obsolete in some regions, having been replaced by the ascending sequence Graneros Shale, Greenhorn Limestone, and Carlile Shale.
The Belle Fourche Formation or Belle Fourche Shale is a fossiliferous early Late-Cretaceous geologic formation classification in Wyoming. Named for outcrops in Belle Fourche River, Wyoming, this unit name is also used in Montana, North Dakota, and South Dakota.
The Whiteaves Formation is a geologic formation in British Columbia. It preserves fossils dating back to the Jurassic period.
The Caton Shales is a geologic formation in England. It preserves fossils dating back to the Carboniferous period.
The Hope Shale is a geologic formation in England. It preserves fossils dating back to the Ordovician period.
The Temeside Shale is a geologic formation in England. It preserves fossils dating back to the Silurian period.
The Ledbury Formation is a geologic formation in Herefordshire, England.
