Scotland and England and the building of mountains of a Himalayan scale to the north west. The Silurian sediments were first buried, then lithified into rock, then folded and uplifted and finally eroded to a horizontal surface before being buried by Devonian sediments washed south from the erosion of the mountains. Further tectonic movements later tilted the whole to its current gentle northward dip.
