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. […]

An alternative view on climate change
Before you start shouting at your magazine, don’t worry, you’re not going to read that I think climate change isn’t happening or that human beings aren’t contributing to it. However, I am going to try […]
The geology of East Greenland
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 […]
Salthill Quarry, Clitheroe: a resource being revitalised
A while ago, SKD published a critique of the poor geoconservation practices on one of England’s most productive Sites of Special Scientific Interest (SSSI) of Mississippian age – the so-called scraped surface at Salthill Quarry, […]
Utah: A Geologist’s Wonderland
Often referred to as the Red Rock Country, the state of Utah boasts some of the most breathtaking landscapes formed from years of erosional artistry. Dominating this impressive landscape is the Colorado Plateau that spans […]
Exploring the Jurassic at Zalas Quarry, southern Poland
The area of southern Poland is well known for its widespread Jurassic deposits, in particular, Middle and Upper Jurassic sedimentary rocks that outcrop in a belt running from south-east to north-west in the area known […]
The Bradshaw Foundation: rock art
For one of the oldest forms of human expression, there is still much uncertainty regarding rock art. What is it? Where is it? How old is it? And what purpose did it serve? The last […]
Pico Partido: volcanic perfection in the Canaries
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 […]
World earthquakes
For millions of people in the western part of Sichuan province in China, the morning of 12 May 2008 started out as a day like any other. People left their homes for work as usual, […]
Thrihnukagigur
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 […]
Urban geology: New Red Sandstone at Amsterdam Airport
In a country with a limited resource of pre-Quaternary geology in outcrop, the Netherlands nevertheless has a wealth of rock types in building stones (Donovan, 2015a; Donovan and Madern, in press), street furniture (Donovan, 2015b) […]
On the trail of Shetland’s Volcano
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 […]
A Journey through Geopark Shetland
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 […]
The geology of the Falkland Islands
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 […]
White Scar Cave
White Scar Cave takes its name from the limestone outcrops or “scars” that overlook the entrance. This part of the Yorkshire Dales National Park is dominated by the ‘Three Peaks’ – Ingleborough, Pen-y-ghent and Whernside. […]
Triassic salt in the High Atlas (Morocco)
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 […]
The Geology of Loch Lomond and the Trossachs National Park
The Loch Lomond and the Trossachs National Park has a unique and very visible geological character. This, and the geomorphological processes that have taken place in the area have been fundamental in shaping the outstanding […]
Windmills and building stones: Antigua, West Indies
In his latest book, Ted Nield (2014) reflects on building stones and what they tell the geologist about where they are. Once upon a time, building stones in Britain were derived locally and told the […]
The geology of the Moray Coast
When most people think of Scotland, the images that come to mind are those of high, heather covered mountains like Ben Nevis, islands like Skye, Arran or Rum, or the endless rugged coastline of the […]
Orphan mine site taken into care
One of New Zealand’s most contaminated sites, the Tui Mine near Te Aroha, is to be cleaned up. The New Zealand budget for 2007 confirmed that NZ$9.88 million was available for the two-year project. The […]
Geology and terrestrial life of the Carboniferous
The Carboniferous Period is a fascinating time in earth history. It spanned 60myrs (359.2 to 299.0mya), towards the end of the Palaeozoic era, falling between the Devonian and Permian. During the Carboniferous, the supercontinent Pangaea […]
Urban geology: A sunny Sunday in Hoofddorp
The last weekend in September 2013 was sunny after more than two weeks of grey skies, rain and even some fog. Saturday was spent as planned, moving bookcases ahead of Karen’s insatiable paintbrush, the walls […]
The end-Permian mass extinction
The end Permian mass extinction occurred 251mya and marked the end of the Palaeozoic era. The loss of life is currently estimated to consist of 95% of the marine fauna and around 70 to 77% […]
Mining in ancient Greece and Rome
Ancient civilizations had a high demand for raw materials, like clay, diverse rocks and, most of all, metals. These were required for buildings, crafts, agriculture, their armed forces, financial concerns, art and culture. Clays and […]
Urban geology: monumental geology
My writings on urban geology are normally centred in the area around my home in Noord Holland, but sometimes I am lucky enough to travel. A personal wish that I have had since I was […]
The artistic reconstruction of palaeoenvironments
Life on Earth has been affected and shaped by geological and astronomical events during the 4.5 billion years since it was formed. Scientists study geological and palaeontological processes to answer some rather fundamental questions. What […]
The Bass Rock, Firth of Forth
From much of the coast along the Firth of Forth in southeast Scotland, and from coastal hills such as Arthur’s Seat in Edinburgh, the impressive piece of rock called the Bass Rock forms a prominent […]
Preserving geological museum collections
It has long been recognised that art and archaeological collections in museums may need specialised conditions and conservation to survive. However, until relatively recently, geological collections have not had the same level of care. Perhaps, […]
Lavas from Hawaiian volcano contain fingerprint of planetary formation
Hikers visiting the Kilauea Iki crater in Hawaii today walk along a mostly flat surface of sparsely vegetated basalt. It looks like parking lot asphalt, but, in November and December 1959, it emitted the orange […]
Stones of Destiny
Time and tide wait for no man and truth is often stranger than fiction. Both these sayings apply to Scotland, especially Argyll with its islands at ‘the edge of the world’. Here, historic stones – […]
