Sue Beardmore (UK) Located amid the scenic Southern Alps, on the Swiss-Italian border, is Monte San Giorgio, a mountain that rose up like many across Central Europe as a result of continental collision between Africa and Europe during the Alpine Orogeny. It is not particularly big or distinct by alpine … Read More
Khursheed Dinshaw (India) In this article, I will briefly deal with the fascinating and relatively recent geological transformation of the Sharjah region of the United Arab Emirates (UAE). Sharjah needs no introduction in terms of it being a popular tourist destination, especially for families. However, very few know how it … Read More
As the author, John McManus, writes: “The East Neuk of Fife was blessed with a mineral resource that was relatively easy to access”. This resource was coal – the driver of the industrial revolution and, even before then, a crucial element to the area’s industrial development from medieval times (or even Roman times) to the late twentieth century.
Dr Trevor Watts (UK) We (my wife Chris and I) enjoyed our fourth visit to Big Island Hawaii in May 2013 so much that we decided to return to the same places in October 2014. We were hoping to see similar events and activities, which we had found particularly interesting … Read More
Khursheed Dinshaw (India) This the second of two articles on the Wieliczka Salt Mine in Poland. The first (Wieliczka Salt Mine of Poland (Part 1)) covered some of the highlights that can be seen there. This one covers some more of these features, but also deals with the geology of … Read More
Dr Mark Wilkinson (UK) I sometimes ask a question to students in an introductory class about geology: “What is the most famous geological site in the world?” For students from the western hemisphere, the Grand Canyon in the USA is a popular choice. However, if you were to ask the … Read More
Paul D Taylor (UK) Myths are traditional stories embodying ancient yet false ideas. At the root of many myths lie unusual events, for example, extreme floods, or mysterious objects such as fossils. Numerous myths about different kinds of fossils can be found in the folklore of many countries around the … Read More
Stephen K Donovan (The Netherlands) and Trevor A Jackson (Trinidad) With a length of only about 240km, Jamaica cannot be considered a large island. It is also relatively ‘young’ geologically, the oldest rocks being only about 140myrs old. This might sound old enough, but contrast it with, for example, rocks … Read More
Dr Robert Sturm (Australia) The mineral, emerald, represents the green variety of the hexagonal silicate mineral beryl, which has the chemical formula Be3Al2Si6O18. Its colour may be interpreted as the result of the addition of vanadium and chromium ions into the crystal lattice. In fact, the etymology of the word … Read More
Stephen K Donovan (The Netherlands) Islands are attractive places to visit, not just for geologists. Nonetheless, for us, they provide three advantages that favour collecting and research in the Earth Sciences. One of the attractions of an island is its small size in comparison with continents. The corollary of this … Read More
Stephen K Donovan (The Netherlands) In July 1979, I was one of more than 20 undergraduate students at the Department of Geology, University of Manchester, to undertake their final year mapping project in the Snowdonia National Park in North Wales. My mapping area was the Yr Arddu Syncline, about 4km … Read More
James Cresswell (UK) Eighty percent of Greenland is covered by ice and, in places, this is up to 3.4km thick. So, Greenland might not immediately spring to mind as a place to go to observe rocks. However, it is a huge country and the ice-free area, at 410,000km2, is nearly … Read More
Dr Trevor Watts (UK) Lanzarote is the easternmost island of the Canaries, less than 100 miles (about 150km) off the coast of Morocco. It is part of Spain, but not officially in the European Union and Pico Partido is a sharp, prominent peak near the centre of the island, between … Read More
Dr Trevor Watts (UK) In 2012, my wife Chris and I booked a volcano tour around the north of Iceland. At the time, it was our third visit to the country, so we knew of extra things we wanted to do. Before joining the group with Volcanic Experiences of Bromsgrove, … Read More
Allen Fraser (UK) For a land area of just 1,468km2, yet within a staggering 2,731km of coastline, Shetland has probably the most complex and diverse geology and geomorphology to be found anywhere in the World. Part of Shetland’s Geopark plan was a suggestion from the community of Northmavine that a … Read More
Allen Fraser (UK) In September 2009, the Shetland Islands were awarded the accolade of becoming the thirty-fifth European Geopark. This is fantastic news for the isles. It acknowledges the importance of Shetland’s incredible geology and creates opportunities to promote it to an international market and develop partnerships with other members. … Read More
Phil Stone (UK) Plate tectonics have produced some surprising juxtapositions, as the earth’s continental fragments have drifted and jostled over the eons. Microplates seem to have enjoyed most freedom of movement and none more so than that supporting the Falkland Islands. Though this archipelago is situated in the south-west corner … Read More
Stephen K Donovan (The Netherlands) and Joe SH Collins (UK) Decapod crustaceans (crabs) are among the most attractive of fossils. Yet, the beautifully preserved specimens seen in museum displays and dealers’ catalogues are in stark contrast with the usual haul of the collector, that is, scraps, commonly claws or (more … Read More
Chellai El Hassane (Morocco), Ghanmi Mohamed (Tunisia) and Doblaas Miguel (Spain) The Triassic terrestrial deposits at the northern edge of the High Atlas near Marrakech are mainly represented by thick sequences of massively layered, red sandstone. These are topped by a formation of silt and pink-brown clay containing large deposits … Read More
It is a wonderful state of affairs that we can not only now write detailed books about planetary geology and geomorphology of the bodies in the solar system, but we can also illustrate them with wonderful photographs.
Almeria is a province in southeast Spain, situated in the furthest southeast part of the Iberian Peninsula. It is a classic area for southern European and Mediterranean Neogene and Quaternary geology.
James O’Donoghue (UK) It’s a Welwitschia! Nestling among 280 million year old fossil tree trunks, this is the rare plant I have been searching for. Two wonders of the natural world – the living, sprawling Welwitschia and the ancient, petrified trees – have fortuitously come together here in Namibia. Separated … Read More
