Abstract:

The Cornubian terrane, a microplate that came into existence during the Variscan orogeny, comprises metamorphosed Devonian and Carboniferous sediments thrust into a massive nappe pile and injected by granites. It extends from the southwest tip of Britain to the base of the continental slope at Goban Spur. The Cornubian terrane remained a prominent massif unaffected by subsidence throughout the Mesozoic, and the development of the superposed and surrounding basins was significantly controlled by the positions of former thrusts and a series of NNW-SSE Variscan dextral strike-slip faults.
