User:Geopersona/Chatsworth Grit

The Chatsworth Grit is a coarse sandstone which outcrops widely throughout the Peak District of northern England and gives rise to numerous significant landscape features within and around the Peak District National Park.

It is one of the uppermost sandstone units within the Millstone Grit Group and dates from the Carboniferous period. Along with other similar sandstones such as the immediately underlying Roaches Grit and Ashover Grit it is assigned to the Marsdenian stage of the Namurian epoch. The Chatsworth Grit underlies the Rough Rock which is the topmost sandstone unit of the Millstone Grit group.

Amongst the many important landscape features for which it is responsible are the dramatic western edges of the Eastern Moors of the Peak District including Stanage Edge, Froggatt Edge, Chatsworth Edge and Gardom’s Edge. In the west it forms Shining Tor, the summit of Shutlingsloe and the crag-fringed Combs Moss amongst others. The outcrop is complex due to repeated folding of the rock sequence along a series of north-south fold axes in the western Peak.
