Recumbent chevron folds in Early Pennsylvania graywacke and shale of the Bude Formation at Millook Havem on the north coast of Cornwall, southwestern Britain, record the development and deformation of the Varsican foreland basin -- testifying to the closure of the Rheic Ocean during the mid- to Late Pennsylvanian Variscan orogeny.

These salt deposits were formed during the “Messinian Salinity Crisis”, a geological event during which the Mediterranean Sea was cut off from the Atlantic Ocean and dried up (or mostly dried up), creating massive deposits of previously dissolved salts. This occurred at the end of the Messinian age of the Miocene epoch, from 5.96 to 5.33 million years ago, ending when the Atlantic again flowed into the basin
