SK1171 : Calton Hill Quarry

near to Blackwell, Derbyshire, Great Britain

Calton Hill Quarry
Calton Hill Quarry
The site is a olivine-dolerite sill, with columnar jointing (Giants causeway style) along with a rare volcanic vent. Volcanic breccias are also in the quarry.
The volcanism was due to Carboniferous rifting events, producing mafic eruptions. What gets geologists excited about this place (which is a SSSI) is the olivine xenoliths brought up from the mantle. Possibly unique in Britain.

The site was quarried for roadstone before being filled with landfill.
