Grey Aberdeen Granite
Aberdeen Granite is Ordovician in age (489 to 442 million years old). The most well known quarry was Rubislaw Quarry which was active from 1740 to 1971 and was considered to be the largest man-made hole in Europe.
Aberdeen Granite is still quarried for aggregate in the Aberdeen area. It is a pale grey or silver granite and the stone was used to construct many of the buildings in Aberdeen (‘the granite city’) as well as being used throughout the UK and exported further afield. Some notable examples of use include: the Forth Bridge and the Houses of Parliament and Waterloo Bridge, London.
