Brownber Formation is part of the Great Scar Limestone Group
The sedimentary rocks of the Brownber Formation comprise interbedded sandstone (fine-grained, pale brown, laminated in part), limestone (calcarenites, grainstones, oolitic in part) and dolostone (yellow and flaggy) containing abundant quartz pebbles in distinctive and laterally discontinuous beds near the top.
Reference sections occur in old quarries north of Bousfield, Park and Dawns (NY 6102 0922 to 6107 0924) including beds of limestone and sandstone (with gaps), at or near the top of the formation, 4.8 m thick; and in a stream section north of Orton Village Green from (NY 6241 0844 to 6243 0851) which includes sandstone and limestone (with gaps) 6.7 m thick (see Pattison, 1990).
Lower and upper boundaries
The sandstones of the Brownber Formation overlie limestones of the Coupland Sike Limestone Member (Scandal Beck Limestone Formation) (Figure.9, Column.16), but the boundary is poorly known in the Ravenstonedale area (see Pattison, 1990; McCormac, 2001).
Within the Stainmore Trough, an unconformity is present at the base of the overlying dark grey limestone of the Breakyneck Scar Limestone Formation which comprises packstone or grainstone with mudstone/siltstone interbeds.
About 15–80 m thickness is recorded in the Orton area with 10–40 m in the Appleby district.
