| Abstract: | The Coniston Limestone Group (Ashgill Series) in the southern Lake District shows greater lithological variation and lateral facies variation than hitherto suspected. The oldest part, the Longsleddale and Stile End Formations, is shown to correlate with the Cautleyan Stage, Zone 2, at Cautley; consequently the entire Coniston Limestone Group in the southern Lake District is considered to belong within the Ashgill Series. In the early Cautleyan, sedimentation was largely influenced by a central ridge which extended northward into a southerly transgressive sea. Later Cautleyan and Rawtheyan sedimentation was affected by an area of positive tectonic activity in the east of the region. |
