Old Harry Rocks Knowledge Organiser #17: Dorset Old Harry Rocks are located on the headland between Swanage and Studland Bay. The headland is made Where? Dorset, UK out of chalk, a hard rock. The headland Case Study Focus: Coastal Landforms juts out into the sea, so it is more vulnerable to high-energy waves. This caused the formation of Old Harry, a stack. Over time Old Harry will collapse Basic facts about Dorset to form a stump. The Dorset coast is famous for its beauty. The Dorset Coast forms part of the ‘Jurassic Coast’ which extends from from Exmouth in East Devon to Old Harry Rocks in Purbeck. The Jurassic Coast was awarded World Heritage Site status by UNESCO for being a place of ‘outstanding universal value’. Through its geology, cliffs, arches, stacks and stumps the coast represents 185 million years of the Earth’s history. The Dorset Coast contains a range of landforms including Durdle Door, Lulworth Cove, Chesil Beach and Old Harry rocks. Dorset is located in the south of England. Its coastline has examples of many erosional and depositional landforms. For Chesil Beach example: Chesil Beach is an example of a bar. Sediment has been deposited over time to form a spit. The spit has continued to Swanage is an example of a headland and bay join to the Isle of Portland. Behind the Old Harry Rocks is an example of caves, stacks and spit there is The Fleet, a lagoon. stumps at Chesil Beach there is a bar Swanage Bay The area around Swanage is made up of bands of hard and soft rock. The soft rock is made of clay and sands, and the hard rock is chalk and limestone. As erosion processes take place, the clay erodes away quicker than the limestone and chalk. Durdle Door – Excellent example of an arch. .

Storms and Coastal Defences at Chiswell This Booklet Provides Information About
storms and coastal defences at chiswell this booklet provides information about: • How Chesil Beach and the Fleet Lagoon formed and how it has What is this changed over the last 100 years • Why coastal defences were built at Chiswell and how they work • The causes and impacts of the worst storms in a generation booklet that occurred over the winter 2013 / 14 • What will happen in the future Chesil Beach has considerable scientific about? significance and has been widely studied. The sheer size of the beach and the varying size and shape of the beach material are just some of the reasons why this beach is of worldwide interest and importance. Chesil Beach is an 18 mile long shingle bank that stretches north-west from Portland to West Bay. It is mostly made up of chert and flint pebbles that vary in size along the beach with the larger, smoother pebbles towards the Portland end. The range of shapes and sizes is thought to be a result of the natural sorting process of the sea. The southern part of the beach towards Portland shelves steeply into the sea and continues below sea level, only levelling off at 18m depth. It is slightly shallower at the western end where it levels off at a depth of 11m. This is mirrored above sea level where typically the shingle ridge is 13m high at Portland and 4m high at West Bay. For 8 miles Chesil Beach is separated from the land by the Fleet lagoon - a shallow stretch of water up to 5m deep.

The Geology Durdle Door, Dorset Chalk Stratigraphy, Sedimentology and Tectonic Structure New Marker Beds
Wessex OUGS Field Guide to Durdle Door, Dorset, May 2018 The Geology Durdle Door, Dorset Chalk stratigraphy, sedimentology and tectonic structure New marker beds Durdle Cove, Dorset looking west over Scratchy Bottom and Swyre Head to Bat’s Head. The line of caves at the foot of the cliff in Durdle Cove is formed on the Durdle Cove Thrust (see also Rowe 1901, Plate III, pp. 16-17). Open University Geological Society Wessex Group Field Excursion Sunday 13th May 2018 Leaders: Rory Mortimore and Jeremy Cranmer Field guide prepared by Rory Mortimore www.chalkrock.com Based on the paper Late Cretaceous stratigraphy, sediments and structure: gems of the Jurassic Coast of Devon and Dorset, England just going into press in the Proceedings of the Geologists’ Association, 2018. 1 Wessex OUGS Field Guide to Durdle Door, Dorset, May 2018 Wessex OUGS Field Trip Durdle Door, Durdle Cove, Scratchy Bottom and Bat’s Head Late Cretaceous stratigraphy, sediments and structure: gems of the Jurassic Coast of Devon and Dorset, England Introduction Extraordinary, long-distance litho-marker beds such as the Lewes and Shoreham Tubular Flints and associated marl seams and fossils (Fig.2), recognised in cliff exposures and cliff-fall boulders, are keys to unlocking the stratigraphy and tectonic structures in the Late Cretaceous (Fig.1) of the Jurassic Heritage Coast. Durdle Cove is a special gem exposing the Lewes and Seaford Chalk stratigraphy where these and new marker beds are identified and where sediments and tectonic structures provide clues to timing of movements that produced a Late Cretaceous pericline which grew into a Miocene monocline along the line of the underlying Purbeck Reverse Fault.
