New mapping of the southern part of the Dent Fault reveals three segments, each 5–6 km long, overlapping at two left-stepping zones 1–2 km wide. The main fault strands probably dip steeply WNW. A faulted footwall syncline in Carboniferous strata indicates reverse dip-slip, with a stratigraphic throw of at least 750 m. Locally developed plunging folds and imbricate fault duplexes developed at fault bends reveal a strike-slip component, indicated to be sinistral from limited slickenline data. Silurian strata in the hanging wall lack the Variscan folds observed further north. The northern overstep hosts up-faulted slivers of older Silurian and Ordovician rocks. The southern overstep zone hosts a younger faulted block compatible with releasing kinematics in sinistral strike-slip.
The Dent Fault converges at its southern end with the Barbon Fault; an upfaulted wedge of Silurian strata lies between them near the branch point. The two faults swing southeastward, joining the Craven fault system via splays and linkages. Regionally, the Dent and Barbon faults form the innermost pair of a fan of ~N–S striking faults splaying off the northwest end of the South Craven–Morley-Campsall Fault System around the southwestern corner of the Askrigg Block.
The kinematics of the Dent, Barbon and Craven faults fit shortening orientated NNW–SSE during late Carboniferous Variscan deformation. The rigid Askrigg Block focussed displacements around its west and south margins where fault and fold orientations were influenced by pre-existing structures, at least Acadian in age to the west and early Carboniferous to the south.
