Excursion to Lyme Regis, Easter, 1906
320 EXCURSION TO LYME REGIS, EASTER, 1906. pebbles and bed NO.3 seemed, however, to be below their place. The succession seemed, however,to be as above, and, if that be so, the beds below bed I are probably Bagshot Beds. "The pit at the lower level has been already noticed in our Proceedings; cj. H. W. Monckton and R. S. Herries 'On some Bagshot Pebble Beds and Pebble Gravel,' Proc. Ceol. Assoc., vol. xi, p. 13, at p. 22. The pit has been worked farther back, and the clay is now in consequence thicker. Less of the under lying sand is exposed than it was in June, 1888. "The casts of shells which occur in this sand were not abundant, but several were found by members of the party on a small heap of sand at the bottom of the pit." Similarly disturbed strata were again observed in the excavation for the new reservoir close by. A few minutes were then profitably spent in examining Fryerning Church, and its carved Twelfth Century font, etc. At the Spread Eagle a welcome tea awaited the party, which, after thanking the Director, returned by the 7.55 p.m. train to London.

Charmouth, Dorset
EAST BEACH (STONEBARROW), CHARMOUTH, DORSET INTRODUCTION TO EAST BEACH Thank you for enrolling on our fossil hunting THE GEOLOGY event. UKAFH return to Charmouth, nestled on The cliffs and foreshore between Charmouth and Seatown, the West Dorset coast and a popular location for fossil collectors, particularl children. Despite between the car park at East Beach, onwards under the tall cliffs under Stonebarrow Hill, which are Stonebarrow towards Golden Cap, represent two stages continuously being eroded by the sea, the within the Early Jurassic (or Lias) period known as the beach is safe and fossils washed from the clay Sinemurian and Pliensbachian, dating from approximately can be picked up from along the foreshore. 190-185 million years ago. Charmouth has access to two main fossil During this time, an enormous, generally shallow collection areas; beneath Black Ven cliffs in the epicontinental sea (less than 100m deep), spread over this west and East Beach (often referred to as area of the world, and laid down alternating layers of clay and Stonebarriow) to the east of the car parks.

Stonebarrow to Seatown Via Golden Cap
Stonebarrow to Seatown via Golden Cap www.footscape.co.uk 07825 720 780 Trail : Stonebarrow to Seatown – 4 miles (6.4 km) Coast Path dips and rises towards Golden Cap, the highest point on England’s south coast. The views from here are breathtaking. At the end of this walk, Seatown, a tiny hamlet boasts an excellent beachside public house which is the perfect lunchtime venue. Many fossils have been found along this stretch of coastline, and although it is not so easy to find anything of significance today, the ongoing instability of the coastline means that there is always the chance of doing so. Unfortunately a series of landslips between Lyme Regis and Charmouth has meant that the coast path is too dangerous to use, and long-term diversions inland have been put in place. Consequently we recommend starting the walk at the National Trust Stonebarrow Hill car park in Charmouth. ► On entering the National Trust car park, turn right following a wooden signpost directing you towards Golden Cap 2¼. Pass through the small wooden gate and follow the path downhill. ► Soon afterwards another track comes in from the right, running parallel to the coast. Continue straight ahead here towards the sea. The path then bends round to the left, but continues downhill. ► At the junction with another track follow the footpath sign to Westhay Farm. So, turn right towards farm buildings, cross the cattle grid (or use the gate) and go past the farm to a gate and continue down towards the coast. At this point you will have a wonderful view of Golden Cap in front of you. -
(Albian) Upper Greensand Formation of the Wessex Basin and South West England, UK
Acta Geologica Polonica, Vol. 68 (2018), No. 2, pp. 161–180 DOI: 10.1515/agp-2018-0003 The stratigraphy of the mid Cretaceous (Albian) Upper Greensand Formation of the Wessex Basin and South West England, UK RAMUES GALLOIS1 and HUGH OWEN2 1 92 Stoke Valley Rd., Exeter, UK. E-mail: [email protected] 2 Department of Earth Sciences, Natural History Museum, Cromwell Rd, London, UK. E-mail: [email protected] ABSTRACT: Gallois, R. and Owen, H. 2018. The stratigraphy of the mid Cretaceous (Albian) Upper Greensand Formation of the Wessex Basin and South West England, UK. Acta Geologica Polonica, 68 (2), 161–180. Warszawa. The Upper Greensand Formation, mostly capped by the Chalk, crops out on the edges of a broad, dissected plateau in Devon, west Dorset and south Somerset and has an almost continuous outcrop that runs from the Isle of Purbeck to the Vale of Wardour in south Wiltshire. The Formation is well exposed in cliffs in east Devon and the Isle of Purbeck, but is poorly exposed inland. It comprises sandstones and calcarenites with laterally and stratigraphically variable amounts of carbonate cement, glauconite and chert. The sedimentology and palaeon- tology indicate deposition in marginal marine-shelf environments that were at times subject to strong tidal and wave-generated currents. The formation of the Upper Greensand successions in the region was influenced by penecontemporaneous movements on major fault zones, some of which are sited over E-W trending Variscan thrusts in the basement rocks and, locally, on minor faults. Comparison of the principal sedimentary breaks in the succession with the sequence boundaries derived from world-wide sea-level curves suggests that local tec- tonic events mask the effects of any eustatic changes in sea level. -

The site includes the previously and separately notified Newlands Batch SSSI. Within Dorset Area of Outstanding Natural Beauty and West Dorset Heritage Coast. The site is contiguous with Axmouth to Lyme Regis Undercliffs SSSI to the west and Chesil and the Fleet SSSI to the east. Much of the site is owned by the National Trust (Golden Cap Estate). The site includes 12 Geological Conservation Review localities. Description and Reasons for Notification: The West Dorset Coast between Chesil Beach and Devonshire Head near Lyme Regis is an internationally important geological site, particularly famous for its fossil reptiles. The varied undercliffs have a wide range of habitats which support a number of rare plants and animals. Adjoining the coastline are unusually large areas of herb-rich grassland of a type now very restricted in occurrence. Geology The seacliffs at this site are of outstanding international importance to geology, and one of the most important British localities. -
Golden Cap, Dorset
Golden Cap, Dorset Place To Walk Location & Access: West Bay is the port town for Bridport, and is found at SY461 904. It can be accessed via the A35 road from Dorchester to the east, and via the A35 road from Lyme Regis to the west. Bridport and West Bay are served by a regular Wessex bus service (number X51). This service is also known as the ‘Jurassic Coaster’. View along Dorset coast from Golden Cap Key Geography: Stunning section of the South West Coast Path - part of the Jurassic Coast World Heritage Site. Cliffs, coastal management, fossils. Description: In order to make a full day of exploration, this 7 mile walk can start at West Bay – setting for the popular TV series ‘Broadchurch’. The south west coast path can be followed from here, climbing Golden Cap (the highest cliff on the south coast) along the way, before the walk ends at the beach at Charmouth. At West Bay, the shingle beach is backed by the impressive sheer wall of East Cliff. Here, horizontal beds of golden Bridport sands alternate with nodules of more resistant calcareous sandstone, which jut out giving the cliffs a serrated appearance. There are some interesting rock armour sea defences to look at before continuing along the coast path to Beach and cliffs at West Bay pass Eype Mouth. After this, you embark on the first steep climb of the walk to the top of Thorncombe Beacon. From here, there is a great view back towards West Bay, and further eastwards along the Jurassic coast towards Weymouth and Portland. -
