==Pinskey Gill Formation [http://www.bgs.ac.uk/lexicon/lexicon.cfm?pub=PNKG (PNKG)], Carboniferous, Northern England Province==
Pinskey Gill Formation is part of the [[Ravenstonedale Group]]
=== Name ===
Derived from Pinskey Gill, by Newbiggin on Lune, Cumbria. The formation was originally named the Pinskey Gill Beds by Garwood (1913, p. 496)<ref name="Garwood13">Garwood, E J.1913.The Lower Carboniferous succession in the north-west of England.''Quarterly Journal of the Geological Society'', Vol. 68, 449–596.</ref>.

=== Lithology ===
The Pinskey Gill Formation comprises grey, vuggy, dolomitic limestone and dolostone interbedded with grey to dark grey calcareous mudstone and thin-bedded, calcareous, silty sandstone.

=== Genetic interpretation ===
The strata were deposited in a peritidal marine and fluvial environment.

=== Stratotype ===
The type section is in Pinskey Gill (NY 698 040) where the formation is about 20 m thick and comprises beds of sandstone, calcareous mudstone with sporadic pebbles, sandy shale, interbedded mudstone and shale, and dolomite, (see Garwood, 1913, pp. 496– 499<ref name="Garwood13"></ref>).

=== Lower and upper boundaries ===
The formation rests unconformably upon a smooth planation surface cut into Lower Palaeozoic strata. Conglomerate beds of the Marsett Formation overlie it unconformably (Figure 9, Column 16).

=== Thickness ===
Up to 50 m.

=== Distribution and regional correlation ===
The formation is found only at Ravenstonedale in the Stainmore Trough.

=== Age and biostratigraphical characterisation ===
Miospores including ''Schopfites claviger'' and ''S. delicatus ''of the CM and possibly PC zones (Johnson and Marshall, 1971<ref name="JandM">Johnson, G A L, and Marshall, A E.1971.Tournaisian beds in Ravenstonedale, Westmorland.''Proceedings of the Yorkshire Geological Society'', Vol. 38, 261–280</ref>; Holliday et al., 1979<ref>Holliday, D W, Neves, R, and Owens, B.1979.Stratigraphy and palynology of early Dinantian (Carboniferous) strata in shallow boreholes near Ravenstonedale, Cumbria.''Proceedings of the Yorkshire Geological Society'', Vol. 42, 343–356.</ref>) and conodonts dominated by ''Bispathodus aculeatus aculeatus, B. stabilis ''and ''Clydagnathus unicornis'' of the ''Pseudopolygnathus multistriatus'' Zone (Varker and Higgins, 1979<ref>Varker, W J, and Higgins, A C.1979.Conodont evidence for the age of the Pinskey Gill Beds of Ravenstonedale, north-west England.''Proceedings of the Yorkshire Geological Society'',Vol. 42, 357–369</ref>; Varker and Sevastopulo, 1985<ref>Varker, W J, and Sevastopulo, G D.1985.The Carboniferous System: Part 1.—.conodonts of the Dinantian Subsystem from Great Britain and Ireland.167–209 in ''A Stratigraphical Index of Conodonts''. Higgins, A C, and Austin, R L (editors). (Chichester: Ellis Horwood Limited for the British Micropalaeontological Society)</ref>) indicate a Tournaisian (mid Courceyan) age for the formation (Table 2).
