Deep structural control on distribution of raised beaches and Quaternary sedimentation in Brittany? A review

The distribution of the Pleistocene/Holocene sediments is compared with the deep structures. The westernmost Alpine undulation controlled the north-south deposition of the recent loess and swamps in eastern Brittany. The Biscay Bay related structure controlled the deposition of loess along the northern coast of Brittany, and also the location of the Pleistocene raised beaches. The gradient in beach age results from the preferential uplift of the westernmost part of Brittany.
