Devon's rocks - a geological guide - Geology

An ‘Introduction to the Geology of Devon’ travels back in time and summarises the history and variety of geology in Devon. A document called ‘Devon’s Rocks – A Geological Guide’ provides a compilation of all 13 rock type guides. The Educational Register of Geological Sites is designed to encourage the educational use of Devon

4.4.1.1 Lower Carboniferous Sandstones and Shales The Lower Carboniferous Sandstones and Shales (also known as the Lower Limestone Shales) rest conformably on the Old Red Sandstone and mark the onset of a marine transgression. The strata comprise a series of sandstones, siltstones and mudstones (Tietzsch-Tyler et al., 1994). They outcrop

The Nercwys association consists of deep stony fine loamy soils in drift derived mainly from Carboniferous sandstones and shales. It is mapped in Clwyd, Devon, Derbyshire, North Yorkshire, Durham, Cleveland and Northumberland. The main soil is the Nercwys series of fine loamy stagnogleyic brown earths in drift with siliceous stones.

The Devon landscape: climate, geology and soils

The landscape of Devon reflects the complexity of interactions between climate, geology, soils and land use that have combined to produce a wide range of plant environments. The diverse flora of the county has adapted to these environments, and continues to change in response to land use pressures and on-going and future climate change.
