Longhoughton Quarry

Longhoughton Quarry is a Site of Special Scientific Interest (SSSI) in north Northumberland in North East England. The site is a now disused quarry which yielded whinstone, a hard dark rock associated in Northumberland with the Whin Sill.

Location and natural features
Longhoughton Quarry is situated 0.9 mi west of Longhoughton, a coastal village in Northumberland. The SSSI covers an area of 6.7 ha. The quarry displays intrusions of the igneous rock dolerite beneath a Great Limestone stratum, and shows variously the incorporation of blocks of sedimentary rock; baking of sedimentary rock, and the delineation of ancient watercourses.

The condition of Longhoughton Quarry was judged to be favourable in 2009.
