Abstract/Summary

This report describes the bedrock geology and structure of the country that lies between the valleys of the River Kent to the west and the River Lune to the east and thus lies between the Lake District and the Howgill Fells. The bedrock stratigraphy is described in section 2. Approximately 2800 m of uppermost Windermere Supergroup rocks of Ludlow age are exposed in the region, belonging to the Coniston Group and succeeding Bannisdale and Kirkby Moor Formations. The Coniston Group is undivided in the area. The former ‘Underbarrow Formation’ has been abandoned as a lithostratigraphical division. The structure is described in section 3. The occurrences of minor intrusions in the area are described in section 4. The lamprophyre dykes are considered to have been emplaced over an extended period during Early Devonian times, whilst the microgranitic bodies (Shap Dyke-swarm) are coeval with the Shap Granite Pluton. Also included are two appendices that update previous mapping on NY40SE and SD49NE. These document in particular changes to the interpretation of the stratigraphy and structure, consequent upon work completed during resurvey of 1: 10 000 sheets SD59 and SD69. Importantly this includes part of the axial region of the Bannisdale Syncline, the southern limb of which is largely faulted out.
