The Geology of Islay
by
David Webster
The Islay archipelago has a great variety of geology: 2-billion-year old gneisses of the Rhinns Complex, a lightly metamorphosed late-Precambrian sedimentary succession including the world-famous Port Askaig Tillite deposited by ice during the time of a ‘Snowball Earth’, lead mines, and igneous rocks from the Silurian, Carboniferous and Palaeocene. Pleistocene glacial features abound, and a recent archaeological dig has found evidence of probably the earliest human occupation of Scotland with ice-age hunters living on Islay some 12,000 years ago. Oh, and we have some nice whiskies too – many with geological stories to tell.
