This is one of the oldest of the GA’s guides and is currently in its third edition (the first having been published in 1957 and the second in 1972). Although there have been changes in classification and so on, the general exposures are largely as good as they used to be – or they were the last time I went!

This is a new guide in Dunedin’s ‘Introducing …’ range of books, covering the branch of geology that studies rock layers (strata) and layering (stratification), primarily in sedimentary rocks, but also layered igneous rocks. In this way, it is intended for students and amateur geologist, rather than the academic earth scientist.

I have to admit that I hadn’t heard of ‘hydrogeology’ before, but I should have. Hydrogeology is an important and vibrant sub-set of geological science, dealing with the distribution and movement of water –groundwater – in the Earth’s soil and rocks. Groundwater transport is one part of the overall hydrological cycle in which water is transferred by evaporation from the oceans and seas into the atmosphere.

I really like the ‘Introducing ….’ series publish by Dunedin Academic Press, as you will have ascertained, if you have read the many reviews I have included in this magazine. This second edition of Introducing Sedimentology by Stuart Jones updates the version I reviewed a while ago (see Book review: Introducing Sedimentology, by Stuart Jones), and I found it equally enjoyable.

The is a second edition of Prof John Cope’s excellent geological guide to the Dorset coast for the Geologists’ Association. It is slightly shorter than the first edition, with some minor corrections and some of the figures revised, together with new photographs. It also now includes the huge quantity of data amassed over last few decades during the hydrocarbon exploration work in the county.

This 4th edition is the first edition of this book to be published with full colour illustrations throughout, and is presented as an enhancement and revision to the text to reflect advances in sedimentology since the publication the 3rd edition. Therefore, I suspect that it retains its place as a leading geological text and reference book for professional geologists and students alike.

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 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.

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.

Almeria is a province in southeast Spain, situated in the furthest southeast part of the Iberian Peninsula. And it is a classic area for southern European and Mediterranean Neogene and Quaternary geology. In fact, it is not far north of the southern boundary of the European tectonic plate and, as a result, has been profoundly affected by the interaction of this and the African plate.

Those of you who have read a few of my book reviews will know that I love geo-guides to small geographical areas, rather than just the big geological scientific issues. In fact, there are lots of good UK guides like this one, to areas such as Dorset and Yorkshire, and many areas of Scotland and Wales, for example. And this is another excellent example of that genre.

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.

Normally, I wouldn’t be interested in semi-precious stones and other pretty things. Personally, I prefer grubbing around in the dirt, perhaps for those far more beautiful, elusive and perfectly formed Cretaceous terebratulids or Silurian trilobites. However, some semi-precious stones have the advantage of also providing a tangible link to the ancient history of life that is so fascinating.

Howgill Fells

This little guide contains excursion guides explaining and exploring the relationship in the UK between hillslope gully erosion and the response by stream and valley systems within the Howgill Fells of Cumbria. The author’s choice of this area rests on the fact that it is one of the most active landscapes in Britain from the point of view of erosion, with the steep slopes of the headwater valleys, which are riddled by networks of erosional gullies that have been active in the relatively recent past.

There are only a few good books on the London Clay and its fossils, but this little guide from the Geologists’ Association is a good start for beginners, children and teenagers. Rockwatch, which published this guide, is the national geology club for young people, the junior club of the GA. Having said that, this guide does not dumb down the information it contains.

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.

This was the first GA guide I ever bought, and I suspect it is still the best. My copy is more than well-thumbed and water-damaged, through many a happy trip to the south of England to collect, what a friend describes as “white fossils in white rock”.
