This slate shows the trade mark stamp of the Easdale Slate Company. The specimen is of Precambrian, Dalradian age. British Geological Survey Petrology Collection sample number EMC 5736. The slate is a typical dark grey colour with a strong&#039;grain&#039;and containing pyrite crystals. This specimen was donated to the Geological Survey of Scotland sometime before 1916. For hundreds of years slate was the preferred roofing material in Scotland. The geological variation found in slate quarries from across Scotland meant that each produced a characteristic slate, with a colour, texture and thickness varying from region to region.
