A Guide to the Geology of Islay was first published in 2015, with minor changes incorporated in the 2017 and 2021 updated editions. A fourth edition (2025) is now available; it is a substantive revision, incorporating new excursions.
A Guide to the Geology of Islay
This guide describes 12 varied excursions on Islay that tell the fascinating story of Islay’s geological past from 2 billion-year old gneiss to the Ice Age.
A Guide to the Geology of Jura
This new guide describes six excursions on Jura that tell the fascinating story of its geological past from 600 million-year-old quartzites to the Ice Age.
The geology of each excursion is described at an introductory level with maps and photographs, and they range from leisurely rambles to more demanding longer walks plus a sea-kayak expedition.
A Guide to the Geology of Colonsay
This new guide describes 5 excursions on Colonsay that tell the fascinating story of its geological past from 2 billion-year-old gneiss to the Ice Age.
Three Geology Books for £25
These guides describe varied excursions on Islay, Jura and Colonsay that tell the fascinating story of their geological past from 2 billion-year old gneiss to the Ice Age.
A Volume II of the Islay Guide was published in April 2021. It included four new excursions on Islay, plus 6 on Jura and 3 on Colonsay. It is now discontinued and has now been superseded in 2025 by two new Guides to the Geology of Jura and of Colonsay.
All three new books can be purchased from the Celtic House bookshop on Islay. The Colonsay book is available in the Colonsay bookshop and the Jura book at the Jura Community Shop.
All three books are available as ebooks on Amazon Kindle
