Recently, I have finished the Great Silurian Controversy, a magnificent book about the nineteenth century arguments over the age of the lower Palaeozoic greywackes/sediments of Devon, and the creation of the concept of the Devonian. And reading The Lewisian: Britain’s oldest rocks by Graham Park, it occurs to me that this should perhaps be called, The Great Lewisian Controversy. It shares the same historical and scientific intentions, and the same grand sweep of scientific history, this time from the early twentieth century – namely, the exploration over decades of the geology of the Lewisian of northwest Scotland.

Dunedin Academic Press has once again added a title to its series of introductions to scientific subjects. This one is a short introduction to an essential subject to any budding geologist (essential, because, as the author points out, 70% of the rocks on the Earth’s service are sedimentary in origin and are of the utmost economic importance to all of us.

I have reviewed some excellent previous guides in this series (Iceland: Classic Geology in Europe 3), but this one is closer to home and covers an area that I have fond memories of from my Munro-bagging days. This is more a companion guide for those walking in the Highlands, especially those on geological field trips.

This is a guide to the collection, preservation and display of fossils from more than 50 locations in the UK. It is unashamedly based on the UK fossils format, but obviously, rather than being an online resource, it is a pocket sized book to be taken and read on site.

I remember reading and enjoying this book when the first edition came out many years ago. I am also a keen hillwalker and have stood on top of many of the Scottish mountains referred to in the text. In fact, I particularly enjoyed climbing Ben More on the island of Mull, which I remember reading was the last volcano in northwest Europe.

Geology of South Wales

I quite like regional guides books, even about areas I haven’t been to and am unlikely to visit. That isn’t the case for South Wales, which is one of my favourite areas in the UK for both scenery and geology. Therefore, this guide is another good addition to my collection and will no doubt accompany me soon on another holiday in the Principality.

For anyone like me who finds the immensity of geological time (‘deep time’) both fascinating and fundamentally difficult – both emotionally and intellectually – this is a great book. Paul Lyle has written it for environmentalists and policy makers to help them explain their concerns and decisions more clearly in the context of geological time, but these are not the only people who should read it.
