Diamonds and What They Can Tell Us About the Deep Earth
By Dr Ekaterina ‘Kate’ Kiseeva (UCC)
Abstract: Diamonds are thought to form in the upper mantle and in the mantle transition zone (410–660 km), and they often incorporate small pieces of surrounding material when they form. These inclusions provide a unique window into the deep mantle, giving researchers much-needed information about the composition of our planet, as well as on the processes which took places millions, even billions, of years ago. In this talk, I will give an overview of deep diamonds and their inclusions: how these diamonds form, what minerals they bring, what they tell us about the composition of the deep mantle, and how they relate to the deep carbon cycle. Additionally, I will give a short overview about the history of diamond discovery throughout the world, including the only diamond ever discovered on the island of Ireland.
Dr. Kate Kiseeva is a lecturer in Geochemistry at the University College Cork (UCC). She obtained her undergraduate degree (2007) in petrology, mineralogy and geochemistry from the State Mining Institute, Saint-Petersburg, Russia. In 2012 she received her PhD in experimental petrology from the Australian National University, Canberra, Australia. For the following 6 years she worked as a postdoctoral researcher and as a NERC independent fellow at the University of Oxford, UK. Kate’s main research interests include the deep carbon cycle, phase transitions in the deep mantle, and the oxidation state of the mantle transition zone. To address these topics, she uses a combination of high-pressure and high-temperature experimental techniques on natural samples, such as mantle xenoliths and inclusions in diamonds.
