Some Unmapped Faults in the Lower Carboniferous of Westmorland and their Relation to the Dent Fault System

Abstract

Summary and Conclusions1. The Dent Fault diminishes in throw towards the north, and is almost non-existent 3 miles south of Kirkby Stephen.2. The principal line of dislocation is then displaced about a mile to the east, where there is a steep monoclinal fold, replaced sometimes by a fault, running in a direction parallel to the Dent Fault and also having a downthrow to the east.3. Further parallel faults, many of them hitherto unmapped, assist in the subsidence of the country to the east.4. Cross-faults, in most cases with downthrow to the south, accommodate the margin of the “Rigid Block” to local increase or decrease of throw.5. These two systems of faults are of approximately the same age, and were brought about by the same crustal movements.
