Rhyolite exploitation in the Cairngorms

Excavations At Chest of Dee, Aberdeenshire have recorded the use of rhyolite for flaked stone tools during the Mesolithic, c.8200BC. Analysis of the flaked lithics suggests that the rhyolite was exploited directly from exposures of this igneous rock. Nearby the site a stream cuts through a vein of rhyolite  – perhaps blocks of this stone were collected here and brought to the occupation beside the waterfall to work into tools.
