The Kvamshesten Basin is a sedimentary basin containing coarse continental clastic rocks of Devonian age. It is one of a series of basins of similar age in southwestern Norway found between Sognefjord and Nordfjord, developed in the hanging-wall of the Nordfjord-Sogn Detachment.[1] It is named for the mountain of Kvamshesten.
