Hi Ykraps, I hope you don't mind me commenting here - PCW told me that you had a major rewrite underway, which is looking good. Only one thing is that the Kimmeridge Clay Formation, Portland Group and Purbeck Limestone Group are mainly Upper Jurassic in age and only reach lowermost Cretaceous at the top; the BGS lexicon of rock units gives the following ranges - Kimmeridge Clay - Kimmeridgian, Portland Group - Tithonian and Purbeck Group - Tithonian to Berriasian. I would be happy to contribute a 'Structure' section or similar describing the faults and folds. Mikenorton (talk) 11:56, 22 July 2012 (UTC)
