The Peak National Park landscape is strongly influenced by the rocks that lie underneath the soil. These are sometimes exposed on the surface as well. These rocks, and the soils formed from them, partly determine which plants will grow on the land and which animals can live there. The rocks also affect the industries that have been important in the Peak District and those that are important now.


Geology of the Peak District National Park


Most of the rocks that now form the surface of the Peak National Park were laid down in the Carboniferous period of geological time. The three main rocks are:-

Limestone, in the south and centre of the Park, forming the White Peak;
Millstone Grit, forming a horseshoe shape around the Park, which is called the Dark Peak;
Shale, a softer rock which lies at the foot of the Millstone Grit edges and forms the fertile valleys of the Park.
