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] References1. ^http://www.bgs.ac.uk/Lexicon/lexicon.cfm?pub=APY BGS Lexicon of named rock units: Appleby Gp {{UK-geologic-formation-stub}}2. ^British Geological Survey 1:625,000 scale geological map Bedrock geology: UK South (5th edn) BGS, Keyworth, Notts 3. ^{{cite web |title=BGS Lexicon of Named Rock Units |url=https://www.bgs.ac.uk/lexicon/lexicon.cfm?pub=BK |website=British Geological Survey |accessdate=19 January 2019}} 2 : Permian System of Europe|Stratigraphy of the United Kingdom |
