In 2010 EGU held our first annual Photo Competition at the General Assembly in Vienna. Since then hundreds of photos have been shared on imaggeo by geoscientists and researchers just like you, with a lucky few being selected each year to be highlighted during the meeting and voted on by our members. These images can be of anything to do with geology or geoscience – we get many beautif ...[Read More]

This image shows benthic foraminifera species of Favulina hexagona (Williamson, 1848) together with nanofossils enclosed inside the shell hexagons. This modern foraminifera species was found in the sediment core retrieved from the western slope of the Rio Grande Rise (western South Atlantic).

This is a transmitted light microscope image of a thin section – a 50-micron thick sliver of rock. This sample was collected from Jebel Hafit, a mountain which straddles the United Arab Emirates and Oman border. Jebel Hafit is approximately 900 m high and is made up of Eocene to Miocene age carbonate rocks which were mainly deposited in a shallow water, tropical setting. More specifically, this im ...[Read More]

Besides for the purposes of documenting my research, I like to take photos of rocks under the microscope also because of their aesthetic appeal. It’s an hidden, marvelous world. These flying-saucer-looking objects are in fact the fossil skeletons of a Nummulites (the larger) and a Discocyclina (the one on top left), both belong to the phylum of Foraminifera. These single-celled organisms occupyied ...[Read More]
