The landscape of the British Isles has undergone dramatic changes during the history of the Earth, from shallow sea to desert to the familiar terrain of the 21st century. In this unit you will explore the processes that have shaped the British landscape over time, gaining insight into the geological evolution of the entire planet.
By the end of this unit you should be able to:
- summarise and identify descriptions of the principal features of the main lithotectonic units of the British Isles, namely the Precambrian Basement, the Caledonian Orogenic Belt, the Variscan Orogenic Belt, the Older Cover and the Younger Cover;
- identify any of the main terranes making up the British Isles on the basis of a description of its age, main rock types, dominant structures, and plate tectonic setting.

Geological processes in the British Isles
This unit provides an introduction to the processes that have shaped the evolution of the Earth, with many detailed examples from the geology of the British Isles. These are studied through the use of the British Geological Survey bedrock geology maps. This unit also helps to give a theoretical foundation for any students considering the residential school for the SXR260 The geological history of the British Isles course, based in the north of England.
This unit is from our archive and is an adapted extract from The geographical history of the British Isles (SXR260) which is no longer taught by The Open University. If you want to study formally with us, you may wish to explore other courses we offer in.
This is an extract from an Open University course which is no longer available to new students. If you found this interesting you could explore more free Geology course units or view the range of currently available OU Geology courses.
