If Yorkshire really is ‘God’s Own County’, then clearly the Almighty is an extremely enthusiastic geologist. Just how lucky is the Yorkshire man who, on the same day, can see some of the best and most varied geology in the world, set out in glorious coastal and mountain scenery, collect superb fossils and minerals, and still be back in the pub in time for some of the best real ale in the UK? That is, Yorkshire is a geological gem that needs a good geological guide.

In recent years, there has been a lot written on the fossils of the UK Chalk. However, this guide was the first and is still probably the best for identifying and learning about the fossils that can be found in the chalk cliffs and pits of the UK.

This is a third, revised edition of a very successful, introductory-level geology guide. In it, the author has taken the opportunity to revise and update the text, and to substitute improved illustrations for some of the old ones.

I don’t normally review BGS memoirs – they are excellent publications, but largely written for the professional or the seriously committed amateur geologist. (I have to admit to owning several, which cover my favourite fossil collecting areas of the UK.) However, this one is a ‘Special Memoir’ that I am quite willing to make an exception for.

The British upper Ordovician has a spectacular variety of invertebrate fossils. The marine communities in which they lived developed on a number of microcontintents and terranes, associated with tectonically active areas of the Earth’s crust.

Back in 1994, Scottish Natural Heritage, together with the BGS, published a guidebook entitled Cairngorms: A landscape fashioned by geology. With the publication of Argyll and the Islands: A landscape fashioned by geology, it has now extended this excellent series to 20 such guides.

The Geologists’ Association has produced yet another great guide, this time on the geology of Wales. However, this is a slightly different beast from most of their other publications. As is always the case with this excellent series of guides, the book describes the geology of different sites capable of being visited. However, this time, the conceit is that visiting the locations is assumed to be by car.

The Caithness area of Scotland is important for its geology, but is also well known for its palaeontology. The Caithness Flagstones are famous for fossil fish and the Helmsdale Fault for the Helmsdale Boulder Beds deposit, beside an active submarine fault scarp. The area even once had its own ‘gold rush’ and you can still try your luck at panning there today at Kildonan.

This is an odd, but nice little book, covering the geology of the Craven Lowlands, an that area is somewhat ignored, geologically. This may be true and, as much of this area is covered by Areas of Outstanding Natural Beauty, it therefore seems a great area for a geologically minded to go to for a holiday.
