Trimdon Limestone Quarry is a Site of Special Scientific Interest in the Sedgefield district of County Durham, England. It lies about 1 km west of the village of Trimdon Grange and about 5 km east of the village of Coxhoe.
The site is an abandoned quarry and exposed to a section of the Ford Formation of Late Permian magnesian limestone. The site is nationally important for an interpretation of the geological history of the Ford Formation carbonates. [1]
The abandoned quarry workings include an area of floristically-rich magnesian limestone grassland, a habitat which is nationally scarce in Britain, with only an estimated 270 ha remaining.[1]
The site is part of a larger area that is managed by the Durham Wildlife Trust as the Trimdon Grange Quarry nature reserve. [2]
