Imaggeo on Mondays: Great Glacial Folds

Whether you’re climbing, hiking or caving, it’s hard to ignore the geology around you. For keen climber and environmental geoscientist Ivan Bour, a trip to the French Alps is no exception… I’ve practiced mountain climbing for a dozen years. During my ascents, I seek geomorphological and geological peculiarities. Very often, I associate my profession as a geologist with my activities in the high mo ...[Read More]

Imaggeo on Mondays: Stars in the Sand

This week’s Imaggeo on Mondays is brought to you by the photographer herself, Jana Eichel, who tells us about her expedition to the Mingsha Mountains and the stunning aeolian landforms that characterise the landscape. This photo was taken during a journey through Asia in spring 2012, which took me across Bangladesh, India and Nepal through to Western China and into the Gobi Desert. This journey al ...[Read More]

Imaggeo on Mondays: The Chalk Cliffs of Étretat

Étretat is a coastal region in northern France, well known for its stunning geological landscape. Particularly the headland you see here. Headland erosion is perhaps one of the best known processes in coastal erosion, where a crack in the headland is opened and enlarged by hydraulic abrasion. Continued wave action causes the widened crack or cave to break through the headland and form an arch. As ...[Read More]

Geosciences Column: Perfecting Palaeogeographic Reconstructions

We model the changes in the geographic location of continents via paleogeographic reconstructions. However, the current methodology for generating these reconstructions is not without problems! Publication of palaeogeographic reconstructions is scarce, probably resulting from the difficulties associated with generating them. Conventional reconstructions are presented as static maps which have poor ...[Read More]
