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 Geologists’ Association have extended their excellent series of geological guides by producing what some people (including me) would think at first was a slightly self-indulgent couple of volumes on ‘Devonshire Marbles’. However, for my part, I soon realised that this view is entirely wrong.

The Geologists’ Association is making something of a name for itself when it comes to pushing the envelope in geological publishing in the UK. It has already produced guides to the geology of non-UK locations and I have reviewed a new guide to the roadside geology of Wales. In itself, that was quite a departure, but so is the book under review – a guide to the ‘urban geology’ of Barcelona.

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 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.
