Rory Mortimore (UK) Flint in the Late Cretaceous Chalk: links across the European platform In a recent issue of this journal Paul Taylor wrote “We are very fortunate in Britain to host one of the most remarkable deposits in the entire geological record, the Chalk” (Deposits Issue 55, 2018, p.35,… … Read More
I have stood several times in front of an (apparently) plain white, chalk cliff-face along with others, while Prof Mortimore discussed the implications of what we were seeing. And, every time, I left not just thinking but knowing this was the most fascinating piece of geology I had ever seen.
Jesse Garnett White (USA) The Waipoua Forest and Parataiko Range I viewed the tilted volcanic outcrops of early Miocene Waipoua Basalt above the Waimamaku River (Fig. 1), then drove into the small town of Waimamaku. I saw a backpacker standing on the sidewalk thumbing a ride holding a paperback in… … Read More
Jan Willem van der Drift (The Netherlands) Historic finds In 1900, nobody knew what kind of tools man used before the handaxe. Some scholars assumed that early-man used ‘eoliths’ – handy natural forms. That theory turned out to be false. The earliest tools were manmade flakes and cores, and this… … Read More
Khursheed Dinshaw (India) The naturally formed rock shelters and caves of Bhimbetka in the state of Madhya Pradesh in India (Fig. 1) have a number of interesting paintings, which depict the lives of the people who lived here (Fig. 2). These rock shelters exhibit the earliest traces of human life… … Read More
The Jurassic Coast Trust has produced a truly fascinating little picture book illustrating the geology of this World Heritage Site.
It has the shape, form and feel of a holiday souvenir book – the sort you buy in tourist information shops to commemorate your visit with pictures of the sites you didn’t have time to see – and there is also plenty of information for the curious visitor who wants to learn more about the earth science of the area.
Dr Neale Monks (UK) The Gault Clay is an Albian (Lower Cretaceous) deposit of blue-grey clay exposed primarily in Southeast England. At the classic exposure at Copt Point, Folkestone, the Gault Clay is sandwiched between the Lower Greensand underneath and the Upper Greensand on top. It is a stiff clay… … Read More
This is a third, revised edition of a very successful, introductory-level geology guide, in which the author has taken the opportunity to revise and update the text, and to substitute improved illustrations for some of the old ones.
Robyn Molan (Australia) In an article in the Australian Age of Dinosaurs Journal (Issue 6, 2008) I dubbed the period between 1984 and 1994 ‘a decade of dedication’, thanks to the persistence of an American-Australian team headed by palaeontologists Tom Rich and his wife, Pat Vickers-Rich. (Tom wrote an article… … Read More
Dr Thomas H Rich (Australia) I have no idea what made me look up at that moment. But, when I did, I saw a flash of light reminiscent of the sun glinting off the wings of a flock of birds abruptly and simultaneously changing direction. However, the light was not… … Read More
There are many good guides the geology of the Lake District and this is no exception. However, this is first and foremost an illustrated guide to the region’s rocks and an introduction to the common rock types to be found, largely through the use of colour photographs.
This is another excellent guide produced by Dunedin Academic press, to go along with the other two reviewed on this page. This one provides, at an introductory level, a succinct and readable guide to metamorphism.
Rosalind Jones (France) In Part 1 (Mull’s famous fossil tree (Part 1): Chrissie and the tree), I described the events surrounding the unique fossilisation of an Eocene redwood tree in Mull’s famous Staffa suite of volcanic rocks. In this part, I will take you on a walk to the fossil… … Read More
Deborah Painter (USA) During the 1700s, when North American colonies were under British rule, a certain highly intelligent and educated man by the name of Thomas Jefferson heard of a remarkable natural arch in west central Virginia, to the southwest of his home in Charlottesville. He purchased hectares of land… … Read More
Sea level change is something that probably everyone who does their best to keep up to date about climate change, thinks they know about and on which they will have an opinion.
Deborah Painter (USA) The island of Greenland is now an independent nation called Kalaallit Nunaat in the language of the native-born people. Almost totally covered in ice, the world’s largest island can be compared to a bowl of ice having a rim of ice-free hills and mountains. The southern tip… … Read More
“When he returned from his voyage, Darwin was already known to its leaders [of all the scientific societies of the metropolis] as a young geologist of great promise, owing to the geological letters he had sent home from South America” (Rudwick 1982, p. 190) This is the second of two… … Read More
Jon Trevelyan (UK) Professor Robert Diffendal Jr’s little guidebook to the Great Plains of the USA makes for a fascinating read for an Englishman like me, who has never been there (but wants to). As he says in his article Great Plains geology: A personal journey, they rarely correspond to … Read More
Alan R Lord (Germany) Palaeontological Association Field Guide to Fossils: Number 15 As the editor of this new publication by the Palaeontological Association (see Palaeontological Association Field Guide to Fossils Number 15: Fossils from the Lias of the Yorkshire Coast), I think that it may be time to explain why… … Read More
Tony Waltham (UK) This article accompanies a book review of Tony Waltham’s book, The World of Geology. The text is broadly taken from the book itself. The world of geology is the world as we know it, that we see and that we live on. It is all about the… … Read More
This is a lovely example of photographs used to inspire and text to explain. For many years, Dr Tony Waltham has produced a photo plus explanatory text for the back cover of the glossy magazine, Geology Today.
This is a new edition of the classic little guide on Blue John by Trevor Ford, who has now sadly passed away. The guide provides a comprehensive overview of the geology and mineralogy of Blue John fluorite from Derbyshire and also provides a description of its mining in the past and today, and its use in the production of ornaments and jewellery.
Mervyn Jones (UK) GA field meeting on 6 and 7 April 2019 This field meeting was the second following the publication of Prof Cope’s GA Guide No 73, Geology of the South Devon Coast (reviewed in Issue 51 of Deposits), the companion to GA Guide No 22, Geology of the… … Read More
Chris Duffin (UK) The Hortus Sanitatis (1491) On 23 June 1491, a new volume was printed and bound for distribution in the German University town of Mainz. The publisher was Jacob von Meydenbach, who might also have been responsible for compiling many of the entries in the book. The volume… … Read More
Steven Wade Veatch (USA) This photograph, taken around 1899, shows my ancestors posing at their modest frame home, where they lived one step away from Cripple Creek’s gold rush world of cardplayers, whisky drinkers, and midnight carousers. The scene depicts my great-grandfather (Robert Pickering Plews), my great-grandmother (Janet Plews), and… … Read More
Just a couple of days before the Covid-19 lockdown, I was with friends at Tidmoor Point collecting wonderful pyrite ammonites from the Oxford Clay with this excellent guide to the South Dorset Coast.
This is a very ambitious work. The authors discuss the geology of Britain as a “geological legacy”, that is, they believe it is “an inheritance bequeathed to 11 millennia or so of its post-glacial inhabitants”.
Andy Gale’s update of his guide to the Isle of Wight (this is the sixth edition) is an important change to an already excellent geological guide. The Geologists’ Association has been updating several of its guides – using a modern format, and providing better colour pictures and diagrams – and this is another great example.
As this book explains, ground conditions for building depend on the history of all these aspects in connection with both the actual building site and the surrounding area. In fact, the book goes into some detail, using colour photographs and block geomodels, to bring the subject to life in what is, I suspect, a somewhat fresh way.
I reviewed some excellent previous guides in this series (Classic Geology in Europe 3: Iceland in Issue 39 and Classic Geology in Europe 12: Almeria in Issue 48), but this one is closer to home and covers an area that I have fond memories of from my Munro-bagging days.
