What Can Diamonds Tell Us About Earth?

Diamonds, thought to form in the upper mantle and the mantle transition zone (410–660 km) 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 processes which took places millions and billions of years ago. Dr. Kiseeva 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.

Kate joined the American Museum of Natural History in November 2023, moving from an academic background. Prior to that sheworked as a Senior Lecturer in Geochemistry at the University College Cork (UCC), Ireland.  In 2012 she received her PhD in experimental petrology from the Australian National University, Canberra, Australia.  Kate’s main research interests include the deep carbon cycle, metasomatism in the cratonic mantle, distribution of trace elements during mantle melting, and oxidation state of the mantle transition zone.
