Brockram
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.
Brockram (basal Breccia) outcrops in the Whitehaven and Workington district (Geological survey of Gt. Britain sheet 28). Saltom Bay gives a good exposure of the Brockram. Along the coast (Saltom Bay to St. Bees ) the thickness of the Brockram varies from 0.75m to 20.5 m. Inland boreholes have revealed the thickness of Brockham to be up to 121 m.
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.
