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.
Once upon a time, I would have said that the only reason to buy this sort of guide is to look at the (black and white) photos of dinosaurs and their bones, and learn about the terrestrial life of what is now the Isle of Wight. However, this is obviously wrong. Of course it is possible for amateurs, as well as professionals, to find dinosaur bones on the beaches of the island.
There are many good guides the geology of the Lake District and this is no exception. It is an illustrated guide to the region’s rocks and an introduction to the common rock types to be found, largely through the use of colour photographs. It also explains how they fit in with the Lake District’s geological history.
The Scottish Borders region is famed for their frontier history, and attendant myths and ballads. This book is concerned with their more ancient geological history, which is revealed by its rocks. These indicate that the area was once on the edge of a huge ocean – the Iapetus – which met its end between the inexorable crush of tectonic plates.
Roderick Impey Murchison must have been a remarkable man. The son of a Scottish landowner, he was one of the first people to rigorously use the principles of stratigraphy discovered by William Smith, which put him in a position to erect the Silurian system and to name about 123myrs of geological time.
When the long awaited PalAss guide to Wealden fossil flora and fauna finally arrived, it was apparent that it was a magnificent tome. It is, by far, the most ambitious and complete of their guides, covering various vertebrate groups, together with invertebrates, plants and stratigraphical descriptions of what can be found on the coast and in the quarries of southern England and the Isle of Wight.
Over a period of 20 years, Ian Tyler has written a series of books on the metalliferous mining industry of the English Lake District and this has clearly been a significant labour of love for him. Unfortunately, Roughton Gill and the Mines of the Caldbeck Fells is his last – the result of the sad loss of his wife and collaborator in this project. However, he has now created an extraordinary record of the geological economic activity in this part of the world.
The first ever fossils I collected were from the spoils tips of the two coal mines in Aberdare, South Wales. Alas, these and most other such spoil tips have been landscaped and covered over. Clearly this was both inevitable and desirable after the closure the UK coal industry, but it is a shame for those of us who love Carboniferous Coal Measures plant fossils.
Recently, the Geologists’ Association kindly sent me three of their new guides to review, and I chose to review Alderney and La Hague: an Excursion Guide first, for some very personal reasons. I remember fondly my visits as a child to Alderney, and my extensive civil engineering works on Corblets beach, building dams of sand to capture the water flowing across the sand into the Race of Alderney.
This is a comprehensive account of the minerals found in the British Isles (including Ireland) and the surrounding islands. At over 600 pages and illustrated throughout by over 550 images (mostly in colour), the book provides exhaustive coverage of the remarkably wide range of minerals found in this part of the world.
Fossils of the Oxford Clay was the fourth published guide by PalAss and covers the eponymous Jurassic Oxford Clay, which has been the major source of brick clay in the UK, notwithstanding the closures of clay pits in the Peterborough area over the years since this was published.
The author, John L Morton, certainly came to popular geological publishing by an interesting and circuitous route. Trained as a pilot, became the district commissioner for scouts in Horsham and, on retirement, studied a BSc in, among other things, geology. In 2001, on the strength of this book on William Smith, he was elected a Fellow of the Geological Society.
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.
There is very little on the fossils of the UK Permian, so this guide was a welcome addition, when it was published in 1988. This was the third of 1988, Palass’s guides to (usually) UK fossils, which the professional and amateur can use to identify and learn about the fossils they have found or want to find.
In this book, you will travel back millions of years in time, as though a time-traveller, to join wildlife safaris and visit ancient environments teeming with life. As the fossils come alive, you will experience and understand the fauna, flora and landscapes seen at localities in the geological past of Scotland.
There are several passions in my life – geology and geomorphology being a couple and hillwalking being another. And it doesn’t take much to see that that these go together rather well. Over the last few years, a number of great leaflets, often laminated, have been produced setting out UK geological walks and these are some more good ones.
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.
It might come as a surprise to the vast majority of the UK population (and probably anyone reading this elsewhere), but this country is a great place for dinosaurs. In fact, it is one of the most important places for Lower Cretaceous dinosaurs, whose remains have been found on the Isle of Wight and in the Weald. A possible Triassic dinosaur has also been found in Morayshire, Scotland, and there are plenty more from the entire length of the Jurassic.
There are several good books on the fossils of the Gault Clay and, by extension, Folkestone. However, this little guide has an advantage over the others that I have looked at.
I have a soft spot for PalAss guides and have reviewed several in the past. As a collector myself, the amount of information about the relevant fossils is second to none, with black and white photos and descriptions of virtually everything the amateur or professional palaeontologist might need.
This latest publication from the British Geological Survey follows the success of its earlier publication, ‘Exploring the Landscape of Assynt’. It consists of a special pack containing both an explanatory booklet and a new 1 : 25,000 scale geological map of the Charnwood Forest and Mountsorrel area.
Like others in the series, Fossils of the Gault Clay has the usual excellent black and white photographs of beautifully prepared specimens. Each chapter is authored by a specialist in the relevant subject, containing an introduction, followed by detailed systematic descriptions of each specimen.
Just a couple of days before the Covid-19 lockdown, I was with friends at Tidmoor Point collecting wonderful pyrite ammonites from the Oxford Clay with this excellent guide to the South Dorset Coast. The South Dorset Coast runs from the West Fleet (of Chesil Beach fame) to and including the Isle of Portland.
The Pentland Hills in Scotland yield a large number of Silurian marine fossils. Although theys are only found within a small area of the Pentland Hills, the formations are extremely rich in fossils.
Increasingly nowadays, the London Clay Formation is becoming a favourite hunting ground for fossils and several good books have been written about it. This guide, written by eminent plant palaeobotanist, Margaret Collinson was the first published by PalAss in its library of guides to (usually) UK fossils for professionals and amateurs.
