Claim: Dent Fault consists of  high and unstable blocks, some of which are underpinned by granitic.
Evidence: The Carboniferous geology of northern England consists of a series of relatively high and stable "blocks", such as the Alston Block separated by actively subsiding "basins", generally referred to as "troughs", such as the Stainmore and Gainsborough Troughs. Some of the blocks are underpinned by granitic intrusions of either Ordovician or Devonian age. The Dent Fault is a major fault zone on the boundary between the counties of Cumbria and North Yorkshire in northern England. The Dent Fault consists of a series of linked steep SSW-NNE trending sub-parallel faults with associated folds.
