Scandal Beck Limestone Formation (SCBL), Carboniferous, Northern England Province[edit]

Scandal Beck Limestone Formation is part of the Great Scar Limestone Group


The name was first proposed by Mitchell (1972)[1] and given formation status by Pattison (1990)[2].


The Scandal Beck Limestone Formation largely comprises dark grey, fine- to medium-grained, variable but commonly quite thin-bedded, packstone. Interbeds of sandstone, siltstone or mudstone between these fossiliferous limestones are common.

Genetic interpretation[edit]

Millward et al. (2003)[3] considered the depositional environment to be a deep water carbonate ramp.


The type area is Scandal Beck (NY.718.040), in the Ravenstonedale area.

Lower and upper and boundaries[edit]

The base of the formation is conformable on the the Algal Nodular Beds at the top of Coldbeck Limestone Formation, the latter comprising well bedded limestones with mudstone partings, and flaggy dolostones with algal macrostructures.

A succession of sandstones, oolitic limestones and layers of quartz pebbles, the Brownber Formation (BNBF), conformably overlies the Scandal Beck Limestone Formation in Ravenstonedale (Figure 9, Column 16).


The formation is about 120 m thick at Ravenstonedale, thinning to the north-east and south-west. It is about 50 m thick in the Appleby district.

Distribution and regional correlation[edit]

The Ravenstonedale area.

Age and biostratigraphical characterisation[edit]

Chadian to early Arundian? (see Mitchell, 1978, fig. 60[4], col..D after Taylor et al., 1971[5]; Ramsbottom in Dunham and Wilson, 1985[6], p. 28; George et al., 1976, p. 39, fig. 11:4[7]; Millward et al., 2003, fig. 7[3]). Stratigraphically significant fossils within the formation include the coral Dorlodotia pseudovermiculare.
