12. The importance of the fossils: Many World Class fossil sites are found within the Site, including those at Lyme Regis and Charmouth. Many World Class fossil sites are found within the Site, including those at Lyme Regis and Charmouth. There are many possibilities for studying fossils, their evolution and importance to geologists as well as their aesthetic value.

18. Land slips. There are also important examples of land slips such as that at Black Ven, the largest in Europe, and the area between Lyme Regis and Axmouth, the first land slip described in technical literature.

21. The development of scientific knowledge: The area has been very important for the development of scientific knowledge, especially in Victorian times, at a time when geology was at the forefront of science. This resulted from the work of such people as Mary Anning, Henry de la Beche and more recently W.J. Arkell.

22. Present day role in education. The coast has an important role in education at present with large numbers of students of all ages coming to the area to study coastal landforms and geology.

23. Out of season tourism. Out of season tourism is an important development as demonstrated by Rockwatch and other events. Out of season tourism is an important development as demonstrated by Rockwatch and other events. What benefits will such out of season tourism provide for the local economy? Study opportunities for students of all ages!

24. Very varied geology: All the rocks in the area are sedimentary in origin but were formed in very varied conditions ranging from arid continental to tropical marine, to lagoonal, to tropical continental and back to marine. All the rocks in the area are sedimentary in origin but were formed in very varied conditions ranging from arid continental to tropical marine, to lagoonal, to tropical continental and back to marine. How can we explain these changing conditions? They can be related to plate tectonic processes.

25. Budleigh Salterton, east Devon. At Budleigh Salterton, the orange coloured sediments were deposited in arid and semi-arid conditions by rivers (perhaps similar to the River Nile in northern Sudan and Egypt) and as sand dunes. At Budleigh Salterton, the orange coloured sediments were deposited in arid and semi-arid conditions by rivers (perhaps similar to the River Nile in northern Sudan and Egypt) and as sand dunes. These sedimentary rocks now dip gently to the east and are found at 1600 metres below east Dorset and form one of the reservoir rocks for the Wytch Farm Oilfield. These sedimentary rocks now dip gently to the east and are found at 1600 metres below east Dorset and form one of the reservoir rocks for the Wytch Farm Oilfield. There are opportunities to relate modern desert environments to ancient ones exposed in the East Devon cliffs. How does the geology affect the development of modern resources? Why do the rocks dip to the east, what has caused the overall pattern of rocks?

26. Lyme Regis. The cliffs either side of Lyme Regis are of Blue Lias, the base of the Jurassic, and formed of inter- bedded limestone and clay. These beds are often very fossiliferous. The cliffs either side of Lyme Regis are of Blue Lias, the base of the Jurassic, and formed of inter- bedded limestone and clay. These beds are often very fossiliferous. What can we tell from the fossil content, how do they help us understand the past?

27. Seatown and Golden Cap. As the rocks dip to the east, progressively younger rocks are seen along the coast, various Lower Jurassic rocks are seen including the Belemnite Marl and Belemnite Stone at Seatown. As the rocks dip to the east, progressively younger rocks are seen along the coast, various Lower Jurassic rocks are seen including the Belemnite Marl and Belemnite Stone at Seatown. Why are some rocks more fossiliferous than others?

28. Golden Cap: The classic Dorset feature of Golden Cap occurs because younger “golden” Cretaceous sandstone rests on older Jurassic grey clay. There is a time gap of around 100 million years, known as an unconformity by geologists.

There is a time gap of around 100 million years, known as an unconformity by geologists. Why is the geological record incomplete?

29. West Bay, evidence of varying conflicts. There are opportunities to study recent changes with the civil engineering project at West Bay and the importance of tourism on coastal towns. Aerial photograph from Dorset, photographic atlas

31. Burton Bradstock. At Burton Bradstock and West Bay distinctive sandstone cliffs occur showing honeycomb weathering. The sandstone dips to the east and also forms a reservoir rock for the Wytch Farm Oilfield. At Burton Bradstock and West Bay distinctive sandstone cliffs occur showing honeycomb weathering.

32. Burton Cliff. Over a period of time the sandstone cliff weathers with harder beds standing out and weaker beds being worn away until cliff falls produce a fresh surface.

Opportunities to study rock forming processes and rock properties such as porosity and permeability as well as mass movement.

33. Cogden Beach. Further east there is a change to clay cliffs and the beginning of Chesil Beach is apparent. Pea grit forms the beach at Burton Bradstock and becomes progressively coarser towards Portland. Further east there is a change to clay cliffs and the beginning of Chesil Beach is apparent. Pea grit forms the beach at Burton Bradstock and becomes progressively coarser towards Portland. Compare and contrast the cliffs – what processes are involved in their formation, what are the rates of process? How did the beach sediment form – study of attrition and related processes.

34. Abbotsbury: At Abbotsbury, Chesil Beach protects the Fleet coastline from erosion. Concern has been raised that the erosion of Chesil Beach will lead to serious erosion problems in south Dorset.

There are opportunities to study wildlife and natural vegetation – shingle and salt marsh plant communities – how do they colonise such inhospitable habitats?

35. The Fleet: Along the Fleet there are various interesting fossil collecting sites including Herbury and Tidmoor Point. At Herbury the Boueti Bed occurs on the beach yielding fossil brachiopods.

37. Portland: Portland shows interesting geology along the coast and in the disused quarries, such as Tout Quarry. In this picture Portland Sand and Portland Stone are seen as well as evidence of land-slips. Portland shows interesting geology along the coast and in the disused quarries, such as Tout Quarry.
