Imaggeo on Mondays: What a thin section has to say about the deformation of the Zagros Mountains

Imaggeo on Mondays: What a thin section has to say about the deformation of the Zagros Mountains

The impressive Zagros Orogeny, as seen from a bird’s-eye view, has featured on Imaggeo on Monday’s blog posts a few times recently. From its fluvial dissection features, through to a false colour LANDSAT 7 image which reveals a velociraptor hiding among fold and thrusts, we’ve looked at the broad scale structures which shape the Zagros mountains. This week, the scale changes entirely: we zoom righ ...[Read More]

Imaggeo on Mondays: Mount Etna

Imaggeo on Mondays: Mount Etna

In this week’s Imaggeo on Monday’s image an almost Martian looking landscape, with ombre coloured soils, gives way to gently rolling hills, covered in luscious woods and vegetation. Were it not for the trees in the distance, you would be forgiven for thinking this image had been captured by a Mars rover. In truth, it is an entirely more earthly landscape: welcome to the slopes of Mt. Etna! Keep on ...[Read More]

Imaggeo on Mondays: The organisation of a river system

The picture shows the Elbe Rivervalley, one of the major rivers of Central Europe. It was taken from the Bastei Bridge close to Rathen, which towers 194 meters above the Elbe River in the state of Saxony in the south-eastern Germany. This region belongs to the national park known as Saxon Switzerland. Together with the Bohemian Switzerland in the Czech Republic, the Saxon Switzerland National Park ...[Read More]

Imaggeo on Mondays: Mountains, rivers and agriculture

This week’s Imaggeo on Mondays image blends a range of geoscience disciplines. The post, by Irene Marzolff, a researcher at Johann Wolfgang Goethe-Universitaet, explores how the mountains, rivers and soils of the High Atlas in Morocco are intrinsically linked to the agriculture of the region. The image was taken in the southern slopes of the Western High Atlas, north of the city of Taroudann ...[Read More]

Imaggeo on Mondays: The place where water runs through rocks

Imaggeo on Mondays: The place where water runs through rocks

Antelope Canyon, located in Arizona, USA, was formed by erosion of the Navajo Sandstone, primarily due to flash flooding and secondarily due to other sub-aerial processes (think of physical weathering processes such as freeze-thaw weathering exfoliation and salt crystallisation). Rainwater runs into the extensive basin above the slot canyon sections, picking up speed and sand as it rushes into the ...[Read More]
