Brockram is a type of rock found in northern England. It is a basal breccia of cemented limestone and sandstone fragments dating from the Permian period, forming part of the Appleby Group.[1]
Brockram outcrops in the Whitehaven and Workington district (Geological survey of Gt. Britain sheet 28). Saltom Bay gives a good exposure of it. Along the coast (Saltom Bay to St. Bees ) its thickness varies from 0.75m to 20.5m. Inland boreholes have revealed its thickness to be up to 121m. [2]
Brockram has been used as a building material in Kirkby Stephen and the rest of the Vale of Eden where it has also been quarried for lime burning. It is visible also beside a river bed under a bridge on the edge of Kirkby Stephen.
