Slavery in the geologic record – Environmental and geomorphological legacies

From 1525, when the first human trafficking ship departed Africa, to September 22, 1862, when the Emancipation Proclamation was issued, more than 300 years passed. This was enough time for the exploitation of humans and the earth to leave a permanent mark, one so profound it is now visible in the geological record. Not only did the age of chattel slavery during the Modern era shape the land and th ...[Read More]

Imaggeo on Mondays: The salt mine carving into the Carpathians

The image gives us a glimpse into the Slănic Salt Mine in central Romania, about 100 kilometres north of the capital city Bucharest. The region was actively mined for almost 30 years, from 1943 to 1970. The Slănic Salt Mine is the largest salt mine in Europe, and the facility consists of 14 large chambers, each more than 50 metres high. The cavities of the mine, more than 200 metres deep, carve in ...[Read More]

What is in your field rucksack? The bag of a mining geologist

Inspired by a post on Lifehacker on what your average geologist carries in their rucksack/backpack, we’ve put together a few blog posts showcasing what a range of our EGU members carry in their bags whilst in the field! Of course, it’s not only research geoscientists who carry kit! Earth scientists in industry often require a number of tools to carry out their daily duties. Today we feature the co ...[Read More]

Imaggeo on Mondays: Drawing in pencil

The picture was taken in Salina Turda, a fascinating salt mine in western Transylvania, in Durgău – Valea Sarată near Turda city. In the picture, the pockets created by salt dissolution can be observed. Over time, due to the erosive power of air currents, the walls have been reshaped: the corners have been rounded and, at the contact between the roof and the walls, a series of dissolution po ...[Read More]
