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 photo is taken at the Pamukkale (meaning “cotton castle” in Turkish), a natural site near Denizli, Turkey. This location is world famous for terraces made of snow-white travertine, a sedimentary rock deposited by water from the hot springs, and a stunning turquoise water color. Close look at the surface texture reveals an extraordinary pattern created by the thermal water slowly f ...[Read More]

This imperfect cube of calcite was formed on the gold surface during the electrochemically assisted scaling process. Once negative electrochemical potential is applied to the gold surface, the oxygen dissolved in water undergoes reduction, yielding hydroxide anions. These anions accumulate at the gold-solution interface, forming a high pH layer. As calcite becomes less soluble with the increasing ...[Read More]
