An improved method of U–Pb dating of vein calcite formed during deformation is used to determine the age and cause of folding along the south coast of England. Fractures arising from folding of Late Cretaceous Chalk of southern England occurred 34.7 ± 1.7 myr ago. Underlying Jurassic strata have veins within fractures with ages of 55, 48–42, 39–37, 34–31 and 25 Ma, with 34–31 Ma being the tectonic culmination. Folding was slightly younger than the age of the youngest strata in the overlying… CONTINUE READING
