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.

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.

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.
