Folding, Dorset

Lulworth Cove is well known for its scenery, rocks and fossils. The rocks in the foreground are thin limestones, formed in warm coastal lagoons & swamps about 135 million years ago (Jurassic Period). Harder limestone forms the foot of the sea-cliffs, but this was breached by wave erosion, allowing the sea to wear away the softer rocks above (to the left of) them.

The orange-brown sandstone in the background contain fossil wood and occasional dinosaur remains; they may have been formed by rivers.

The spectacular folding in the cliff, forming an anticline and a syncline, occurred around 50 million years ago, around the time the Alps were being formed.
