Geology & landscape

Geological Period: Carboniferous · Rock Type: Sandstone

Description

Area, 0.73 ha. 1.8 ac. Description The stream section at Jumble Coppice exposes two thick sandstone layers known as the Ashover and the Chatsworth Grits which were laid down by large river deltas some 315 million years ago during the Carboniferous Period of geological time. Two important bands of shaly sediments, which were laid down under the sea, occur between the sandstones and contain distinctive coiled fossils known as goniatites. Those which occur at Jumble Coppice are of great importance to geologists as they enable accurate datings to be made of the rocks which occur there and which can be shown to belong to the subdivision of the Carboniferous Period which is known as the Marsdenian Stage.
