Local Geodiversity Sites are places where the variety of geology of the local area can be enjoyed and appreciated. In Edinburgh, 30 sites have been designated as Local Nature Conservation Sites by the City of Edinburgh Council and included in the City Local Development Plan.
Edinburgh’s dramatic landscape has been shaped over millions of years by ice wind and rain to what we see today. There are two contrasting rock types across the city, sedimentary and igneous. The sedimentary rocks were deposited 300-360 million years ago in shallow seas and river systems, and currently make up the city’s low ground. The igneous rocks found in Edinburgh can be dated back to two different volcanic episodes, firstly in the Devonian (earlier than 400 million years ago) and then 70 million years later in the Carboniferous. The older of the two form the solid bedrock of the Pentland Hills and consist of complex layering of lava and ash. The younger event gave rise to many volcanic domes including Arthur’s Seat. Towards the later stage of this volcanism, it became more common for magma to erupt underground between rocks forming sills that we can now see today on Corstorphine Hill.

These descriptions and photographs of Edinburgh’s Local Geodiversity Sites were prepared by Oliver Buchanan in a project with the City of Edinburgh Council. This was the ‘Geoscience Outreach and Engagement’ module of Oliver’s final year BSc Geology course at the School of Geosciences at University of Edinburgh.
