A new interpretation for the Variscan structure of SW Devon is presented in the form of a structural cross-section. It is argued that the lowest outcropping part of the Lower Devonian, the Dartmouth Beds, has been transported northwards (NW to NNW) over the upper part of the Lower Devonian and the Middle Devonian. It is also suggested that the Middle Devonian (including the Plymouth Limestone) is thrust northwards over the Upper Devonian. Both these thrusts have previously been recognized in SE Devon.
