| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: The Gastrioceras cumbriense Marine Band generally does not exceed 60cm in thickness. The band is split into five units, the lower barren shales (Unit 1), the advance shales (Unit 2), the acme shales (Unit 3), the retreat shales (Unit 4), and the upper barren shales (Unit 5). | |||||
Lithology and environment
| Primary lithology: | deformed bedding,pyritic,black lithified "shale" |
| Includes fossils? | Y |
| Lithology description: Unit 3: The continuing transition and deepening of the sea caused a rapid transition to conditions of black paper shale deposition. The development of the shale appears to be synchronous as it contains a consistant pelagic fauna and has a widespread spatial distripbution throughout the north of England. The shales display planar stratified bedding planes with a spacing of 0.5 to 0.75 mm. There is little evidence for wave or current activity or bioturbation. At all localities the presence of pyrite blebs around which stratification is deflected is believed to indicate primary pore filling as a shallow depth of burial in tyhe sulphate reduction zone. ... The fauna of the balck shale is dominated by the thickshelled goniatite phase at the four easterly localities, whereas a more diverse benthic assemblge occurs as the two westerly localities [does not include Oxenhope Moor], wherethe thin-shelled Anthracoceratites and Posidonia predomminate over Gastrioceras. At Oxenhope and Dearden Moors the black shale is divided into two by a wavy-stratified grey shale with a much sparser fauna. The reduction in fossil abundance suggests that the grey shale represents a brief interruption of deposition from suspension by sediment-laden currents. | |
