The Dalradian is a geological term describing a series of metamorphic rocks, typically in the high ground lying southeast of the Great Glen of Scotland. It was named after the old Celtic region of Dál Riata (Dalriada) by the geologist, Sir A Geikie, in 1891, and the term now covers a range of metamorphic rocks.

Anglesey contains a fascinating variety of rock types and geological structures, best exposed in a magnificent coastline. The bedrockgeology of Anglesey comprises a complex collage of igneous, sedimentary and metamorphic rocks that were formed between 300 and 650 million years ago.
I like the GA guides. They are excellent resources for amateurs and professional geologists alike. I frequently browse mine, planning geological trips I will probably never take, because I live in geological unexciting London. Therefore, imagine how pleased I was to receive a GA guide to the Great Metropolis to review.
For a long time, Watchet has been known as a superb location for those interested in both fossils and geology, but, surprisingly, the location has had little in the way of media attention. However, within the last couple of years, this area has begun to attract a lot of interest and this little book will further increase its growing popularity.
Geologists’ Association Guide No 2 Compiled by Frank Moseley The Lake District is obviously a prime UK holiday hotspot and, each year, thousands of people visit to enjoy the walking and scenery. Equally obvious is the fact that these activities are possible as a direct…
This GA guide was first published in 1995 and is a great example of the sort of guide that the association still produces – coverage of small(ish), but important areas, where the geology is both fascinating and important. This one contains general descriptions of the geology and geomorphology of this part of west Wales, with 19 separate itineraries, written by 11 experts in their fields.
Andy Gale’s update of his guide to the Isle of Wight (this is the sixth edition) is an important change to an already excellent geological guide.
I have to admit, I was beginning to wonder where Prof Rory Mortimore’s update of his excellent Chalk of Sussex and Kent was. And now I know. It wasn’t a second edition he was working on, but this magnificent magnum opus in two volumes covering a vastly greater area than that other guide. And the wait was more than worthwhile. The thoroughness, writing quality, content and publication standards are superb.
This is the much anticipated 4th edition of the GA’s Yorkshire Coast guide and it was well worth the wait. From personal experience, I was aware that the previous editions were extremely good for any geologist – professional, academic or amateur – who is attracted by the wonderful scenery and fascinating geology of this part of the UK coastline. However, this new edition is altogether an even better product.
This is an interesting guide for someone like me who lives in the Southeast of England. In fact, I have commuted from London to Brighton by train, which took me through a cross-section of the Weald, which is the subject matter of this guide.
This is another of the GA’s short guides, being only 21 pages long and therefore easy to put in a cagoule pocket. Importantly, the five excursions described in the guide are centred on the city of Plymouth. Therefore, the logistics necessary to visit the itineraries should be relatively easy.
This GA guide is stated to be a “Geology Teaching Trail”. Well, it may be, but when I ambled along the trail with the guide in my hand, I certainly wasn’t in a teaching situation. Rather, I was out for a nice walk and a guide to explain what I was seeing. And it did just that and the classic Silurian/Ordovician unconformity you can see was just that. Classic!
West Dorset is rightly famous for its fossils, but few people visit its wonderful, fossiliferous cliffs to look at them as landforms, rather than as an endless source of ammonites and belemnites. This guide does just that and, covers a series of itineraries in the context of landform type.
Shropshire is one of my favourite areas for both geology and fossil collecting. The Silurian of this beautiful area is fascinating and, if you can get permission to get into one of the commercial quarries (and you will need permission), then the results will be remarkable.
This GA guide is intended as a major guidebook to the exposures of highly significant Precambrian, Carboniferous and Permo-Triassic sediments, through to Jurassic rocks of the East Midlands. Personally, it is an area I only partly know (I know Edale in the Peak District quite well) and, for that reason, is an interesting set of locations for me.
This is another lovely guide by the GA to an area that perhaps readers would not associate with good geology. But, of course, that is because of its title, because the areas like Pendle Hill and Derbyshire are wonderful, not just to visit for their geology, but also for their holiday appeal.
This is one of GA’s little guides to a very specific area. This one is West Cornwall, a holiday destination that I recently visited during which I spent some time looking at the geology, along with the gardens and archaeological sites.
The aim of the guide is to help professional and interested amateur geologists to investigate the rocks themselves and to put them in a modern scientific context.
This is one of the oldest of the GA’s guides and is currently in its third edition (the first having been published in 1957 and the second in 1972). Although there have been changes in classification and so on, the general exposures are largely as good as they used to be – or they were the last time I went!
The is a second edition of Prof John Cope’s excellent geological guide to the Dorset coast for the Geologists’ Association. It is slightly shorter than the first edition, with some minor corrections and some of the figures revised, together with new photographs. It also now includes the huge quantity of data amassed over last few decades during the hydrocarbon exploration work in the county.
This is the second Geologists’ Association guide by Professor John Cope. The other is the second edition of his excellent Dorset guide. And, on the grounds that “if it ain’t broken, don’t mend it”, this guide to the south Devon coast follows the highly successful basic plan of that other guide, including the extensive use of colour photos and diagrams.
This is another of GA’s guides, this time to the geology and geomorphology of the popular holiday destination of the Castleton Area in Derbyshire. I love this area and have visited there both for the geology and the beautiful scenery.
The 71st GA guide is not really my area (I prefer palaeontology) and it covers quite a specialist subject, but it is definitely interesting. And this is surely the point of GA guides – to cover topics that other publishers might be reluctant to consider.
There are only a few good books on the London Clay and its fossils, but this little guide from the Geologists’ Association is a good start for beginners, children and teenagers. Rockwatch, which published this guide, is the national geology club for young people, the junior club of the GA. Having said that, this guide does not dumb down the information it contains.
This was the first GA guide I ever bought, and I suspect it is still the best. My copy is more than well-thumbed and water-damaged, through many a happy trip to the south of England to collect, what a friend describes as “white fossils in white rock”.
