The Appleby Group is a lithostratigraphical term referring to the succession of Permian Period aeolian and fluviatile rock strata which occur in northwest England and beneath the Irish Sea in the United Kingdom.[1]
The Appleby Group unconformably overlies a variety of older rock strata (Carboniferous). It is succeeded (overlain) by the Cumbrian Coast Group[2] Its lowermost sub-unit is the Brockram, a breccia which sits unconformably on a range of older strata.[3]
