The geology of Great Britain is renowned for its diversity. As a result of its eventful geological history, Great Britain shows a rich variety of landscapes across the constituent countries of England, Wales and Scotland. Rocks of almost all geological ages are represented at outcrop, from the Archaean onwards.
The geological structure of Great Britain is complex, resulting as it does from a long and varied geological history spanning more than two billion years. This piece of the Earth's crust has experienced several episodes of mountain building or 'orogenies', each of which has added further complexity to the picture.
Column 4 indicates on which 1:50,000 or 1" scale geological map sheet published by the British Geological Survey (BGS) the fold is shown and named (either on map/s or cross-section/s or both). 'E&W' signifies the series of sheets published to cover England and Wales.
UK's topography As this geological map of Great Britain demonstrates, the geology of the UK is varied and complex. The physical geography of the UK varies greatly. England consists of mostly lowland terrain, with upland or mountainous terrain only found north-west of the Tees–Exe line.
In 1965, it was merged with the Geological Museum and Overseas Geological Surveys, under the name of Institute of Geological Sciences. [3] On 1 January 1984, the institute was renamed the British Geological Survey (and often referred to as the BGS), a name still carried today. [4] Since 1835, there have been 20 directors of the survey.

The geology of England is mainly sedimentary. The youngest rocks are in the south east around London , progressing in age in a north westerly direction. [ 1 ] The Tees–Exe line marks the division between younger, softer and low-lying rocks in the south east and the generally older and harder rocks of the north and west which give rise to ...
