Great Scar Limestone Group
The Great Scar Limestone Group is a lithostratigraphical term referring to a succession of generally fossiliferous rock strata which occur in the Pennines in northern England and in the Isle of Man within the Tournaisian and Visean stages of the Carboniferous Period. It is contained within the Carboniferous Limestone Supergroup. Basinal successions Stainmore Trough The sequence in the Stainmore Trough is thus (youngest at top): * Ashfell Sandstone (Arundian age) * Breakyneck Scar Limestone (Arundian age) * Red Hill Formation * Brownber Formation (Chadian age) * Scandal Beck Limestone (Chadian age) * Coldbeck Limestone (Chadian age) On the Alston Block corresponding to the North Pennines, the sequence contains the Melmerby Scar Limestone Formation. Orton area In the Orton area, the sequence is: * Knipe Scar Limestone * Potts Beck Limestone * Ashfell Limestone * Ashfell Sandstone * Breakyneck Scar Limestone * Brownber Formation * Scandal Beck Limestone * Co ...

Group (stratigraphy)
In geology, a group is a lithostratigraphic unit consisting of a series of related formations that have been classified together to form a group. Formations are the fundamental unit of stratigraphy. Groups may sometimes be combined into supergroups. Groups are useful for showing relationships between formations, and they are also useful for small-scale mapping or for studying the stratigraphy of large regions. Geologists exploring a new area have sometimes defined groups when they believe the strata within the groups can be divided into formations during subsequent investigations of the area. It is possible for only some of the strata making up a group to be divided into formations. An example of a group is the Glen Canyon Group, which includes (in ascending order) the Wingate Sandstone, the Moenave Formation, the Kayenta Formation, and the Navajo Sandstone. Each of the formations can be distinguished from its neighbor by its lithology, but all were deposited in the same vast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratum
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and ''lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Alston Block
The Alston Block is a term used by geologists to describe the geological structure of the North Pennines of northern England and which forms a part of the Pennine Block & Basin Province which originated during the Carboniferous period. It is defined by the Stublick and Ninety Fathom faults to the north, the Pennine Fault to the west and the Stainmore Trough to the south. It is in essence a horst underlain by the Weardale Granite which provides sufficient buoyancy to maintain this piece of the upper crust as an area of raised relief. To its west lies the Vale of Eden and to its north is the half-graben of the Northumberland Trough.British Geological Survey. 1996, ''Tectonic Map of Britain, Ireland & adjacent areas'', Pharaoh et al. 1:1500 000 (Keyworth, BGS) The area is also known for its mineral wealth. See also Geological Structure of Great Britain The geological structure of Great Britain is complex, resulting as it does from a long and varied geological history spanning ...
