Geologists’ Association Guide No 73
By John CW Cope
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.
An introduction covers the geology of the area, taking the reader through the regional context and the rock succession from the Devonian through to the Carboniferous, Permian, Jurassic and Cretaceous, to the Palaeogene, together with advice on safety, literature, equipment and access. It then covers several itineraries heading eastwards to the Dorset county border and includes some inland areas, which provide access to features not available on the coast.
The itineraries include the Torquay and Brixham areas, the Permian succession between Torquay and Dawlish Warren, the Permian and Triassic succession east of the River Exe, the Triassic and Cretaceous from Branscombe to Culverhold Point, and certain inland localities.
The area provides an ideal introduction to fieldwork for students and lovers of geology. There is a range of geological features superbly displayed in rocks, together with spectacular structures and a wide range of sedimentary rock types. There is also a good variety of igneous rocks, for example, the Dartmore granite.
This is a new guide. The GA has never produced a book on this area before and, as far as I am aware, there are few other such books on the market. Therefore, if you are interested in this area (and a brief perusal of the guide will show that there is much to be interested in), this is well worth getting.
It is small enough to fit in a coat pocket when exploring the locations and, for this guide, the ring binding works, as it is shorter than the Dorset guide. I recommend it.
