"In the Arkaig district of Inverness-shire [northwest Scotland] there is a well-defined suite of camptonite-monchiquite dykes, and several of them have been observed to be displaced laterally along sinistral faults. This provides direct evidence of transcurrent faulting in Permian or post-Permian times. Similar faulting may have occurred along the major northeasterly fracture lines of the Highlands." Additional information on the occurrence and distribution of the dikes is presented in the discussion.
