Worbarrow Bay is a large broad and shallow bay just to the east of Lulworth Cove on the Isle of Purbeck, Dorset, England.
Worbarrow Bay is a large broad and shallow bay just to the east of Lulworth Cove on the Isle of Purbeck, Dorset, England.
Worbarrow Bay is located about six kilometres south of Wareham and about 16 kilometres west of Swanage. At the eastern end of the Bay is a promontory known as Worbarrow Tout. The northwest end of the bay is known as Cow Corner. Towering over Worbarrow Bay to the north is Flower's Barrow ridge, which due to coastal erosion is gradually falling into the sea. Flower’s Barrow forms the western end of the ridge which runs all the way to Ballard Point, north of Swanage.
Worbarrow Bay is only accessible when the Lulworth Ranges are open to the public. It can be reached by a 1.4-kilometre (0.9 mi) walk down an easy track alongside Tyneham Gwyle, from the car park alongside the ghost village of Tyneham. The residents of Worbarrow were required to leave their homes in 1943, including the Miller family who had lived at Worbarrow for many generations. Little evidence now remains of the eight cottages and coastguard station (disbanded in 1910) that once stood close to the bay.
The geology of Worbarrow Bay and Mupe Bay are very similar and they almost mirror each other. The plane of the "mirror" bisects the point where the two bays meet, the Arish Mell gap.
The cliffs behind Worbarrow Bay expose a sequence of Cretaceous rocks. These range from the chalks at the northwest end of the bay, at Cow Corner, that are between 85 and 145 million years old, through to the hard stone outcrop in the east. The sediments that form the peninsula are Portland limestones, which is 150 million years old, and the Purbeck Beds, 147 million years old.
The cliffs and the tout have distinctive angular layers of rock that visibly demonstrate the complex sedimentary folding that affected this area some 30 million years ago. The foldings were caused by tectonic pressures as the African and European continents collided. At that time the cliff sediments were twisted horizontally and that is why the younger chalks are found towards the rear of the bay and the older sediments face the sea at the front of the bay.
The localities along the Jurassic Coast include a large range of important fossil zones. The Purbeck lagoonal limestones and the shales that are exposed in the cliffs of Worbarrow Tout contain dinosaur footprints and have abundant brackish water bivalves, gastropods and ostracods. [1]
The Isle of Purbeck is a peninsula in Dorset, England. It is bordered by water on three sides: the English Channel to the south and east, where steep cliffs fall to the sea; and by the marshy lands of the River Frome and Poole Harbour to the north. Its western boundary is less well defined, with some medieval sources placing it at Flower's Barrow above Worbarrow Bay. According to writer and broadcaster Ralph Wightman, Purbeck "is only an island if you accept the barren heaths between Arish Mell and Wareham as cutting off this corner of Dorset as effectively as the sea." The most southerly point is St Alban's Head.
Durdle Door is a natural limestone arch on the Jurassic Coast near Lulworth in Dorset, England. Although privately owned by the Lulworth Estate, it is open to the public.
Purbeck was a local government district in Dorset, England. The district was named after the Isle of Purbeck, a peninsula that forms a large proportion of the district's area. However, it extended significantly further north and west than the traditional boundary of the Isle of Purbeck which is the River Frome. The district council was based in the town of Wareham, which is itself north of the Frome.
Dorset is a county in South West England on the English Channel coast. Covering an area of 2,653 square kilometres (1,024 sq mi); it borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The great variation in its landscape owes much to the underlying geology, which includes an almost unbroken sequence of rocks from 200 to 40 million years ago (Mya) and superficial deposits from 2 Mya to the present. In general, the oldest rocks appear in the far west of the county, with the most recent (Eocene) in the far east. Jurassic rocks also underlie the Blackmore Vale and comprise much of the coastal cliff in the west and south of the county; although younger Cretaceous rocks crown some of the highpoints in the west, they are mainly to be found in the centre and east of the county.
Tyneham is a ghost village and former civil parish, now in the civil parish of Steeple with Tyneham, in south Dorset, England, near Lulworth on the Isle of Purbeck. In 2001 the civil parish had a population of 0. The civil parish was abolished on 1 April 2014 and merged with Steeple to form Steeple with Tyneham.
The Purbeck Hills, also called the Purbeck Ridge or simply the Purbecks, are a ridge of chalk downs in Dorset, England. It is formed by the structure known as the Purbeck Monocline. The ridge extends from Lulworth Cove in the west to Old Harry Rocks in the east, where it meets the sea. The hills are part of a system of chalk downlands in southern England formed from the Chalk Group which also includes Salisbury Plain and the South Downs. For most of their length the chalk of the Purbeck Hills is protected from coastal erosion by a band of resistant Portland limestone. Where this band ends, at Durlston Head, the clay and chalk behind has been eroded, creating Poole Bay and the Solent. The ridge of steeply dipping chalk that forms the Purbeck Hills continues further east on the Isle of Wight.
The Purbeck Group is an Upper Jurassic to Lower Cretaceous lithostratigraphic group in south-east England. The name is derived from the district known as the Isle of Purbeck in Dorset where the strata are exposed in the cliffs west of Swanage.
Pondfield Cove is a small, secluded, south-facing cove immediately to the east of Worbarrow Tout and west of Gad Cliff on the south coast of the Isle of Purbeck, in Dorset, England. It is about 12 kilometres (7.5 mi) south of Wareham and about 16 kilometres (10 mi) west of Swanage.
Worbarrow Tout is a promontory at the eastern end of Worbarrow Bay on Isle of Purbeck in Dorset on the south coast of England, about 6 kilometres (3.7 mi) south of Wareham and about 16 kilometres (10 mi) west of Swanage. Immediately to its east is Pondfield Cove.
Cow Corner is the north-western end of Worbarrow Bay, a small secluded bay on the south coast of the Isle of Purbeck, in Dorset England.
Flower’s Barrow is an Iron Age hillfort, built over 2500 years ago, above Worbarrow Bay in Dorset on the south coast of England.
The Purbeck Monocline is a geological fold in southern England. The term 'fold' is used in geology when one or more originally flat sedimentary strata surfaces are bent or curved as a result of plastic deformation. A monocline is a step-like fold, in which one limb is roughly horizontal. The Purbeck Monocline was formed during the late Oligocene and early Miocene epochs, about 30 million years ago. It is the northernmost 'ripple' of the Alpine Orogeny.
Gad Cliff is a south-facing cliff face, immediately to the east of Worbarrow Tout and Pondfield Cove, on the south coast of the Isle of Purbeck in Dorset, England. Behind it is Gold Down, part of the Lulworth Ranges.
Brandy Bay is a small secluded southwest-facing bay, with an oil shale and shingle beach immediately below Gad Cliff and Tyneham Cap, to the east of Worbarrow Bay and to the west of Hobarrow Bay on the south coast of the Isle of Purbeck, in Dorset, England.
Hobarrow Bay is a small secluded southwest-facing bay, with an oil shale and shingle beach to the southeast of Brandy Bay and to the southwest of Kimmeridge on the south coast of the Isle of Purbeck, in Dorset, England.
Dorset is a county located in the middle of the south coast of England. It lies between the latitudes 50.512°N and 51.081°N and the longitudes 1.682°W and 2.958°W, and occupies an area of 2,653 km2. It spans 90 kilometres (56 mi) from east to west and 63 kilometres (39 mi) from north to south.
Povington Hill, at 198 metres (650 ft) high, is one of the highest points on the chain of the Purbeck Hills in south Dorset on the southern coast of England. Its prominence of 107 metres (351 ft) means it is listed as one of the Tumps, although map sources suggest this honour should go to Ridgeway Hill further east.
Arish Mell is a small embayment and beach between Mupe and Worbarrow Bays in Dorset, England and is part of the Jurassic Coast and the South West Coast Path passes just to the north. It is about 1 mile (1.6 km) due south of Lulworth Castle and East Lulworth. The bay is relatively inaccessible because it is within the Lulworth Ranges, an Army tank firing range, and although the Range Walks are open at most weekends and public holidays, there is no public access to the beach and cliffs.
The Lulworth Formation is a geologic formation in England. It dates from the late Tithonian to the mid Berriasian. It is a subunit of the Purbeck Group. In Dorset, it consists of three members, which are in ascending order, the Mupe Member, the Ridgway Member, and the Warbarrow Tout Member. The Mupe Member is typically 11 to 16 m thick and largely consists of marls and micrites with interbeds of calcareous mudstone. The Ridgeway Member is about 3 to 7 m thick and consists of in its western portion carbonaceous muds, marls and micrites, in the east the muds are replaced by micritic limestone. The Warbarrow Tout Member is 17 to 39 m thick and consists of limestone at the base and micrite and mudstone for the rest of the sequence, this member is the primary source of the vertebrate fossils within the formation. Elsewhere the unit is undifferentiated.
