Summary:Apatite fission-track data from a W-E transect across N Corsica imply late early Miocene crustal exhumation. Resetting of samples from the Alpine orogenic wedge, adjacent foreland basin and crystalline basement implies removal by erosion of a 2.0-2.3 km thick crustal section, comprising thrust sheets and/or autochthonous foreland deposits, since the early Miocene. A westerly projection of this lost cover shows N Corsica was covered either by Alpine nappes, or Middle Eocene foreland deposits. Similar fission-track ages across the main boundary fault separating the Alpine orogenic wedge and foreland implies no significant differential vertical displacement of the upper and lower plates during Neogene unroofing.
