New open access paper by me: Oxygen in the Earth’s mantle

Triple oxygen isotopic composition of the high-3He/4He mantle

Published Open Access in Geochimica et Cosmochimica Acta, Volume 176, 1 March 2016, Pages 227–238.

I promise to write an explainer on this research soon because I realise the title of the paper is not particularly friendly to non-specialists (to say the least). This project relates to work I was doing during my PhD, looking deep into the Earth’s mantle by analysing samples of ancient volcanoes, but I just couldn’t leave it behind. Because I’m a geochemist I like to try to analyse every element I can, and we hadn’t done oxygen isotopes in these samples so a few years later it’s now done. There is of course a good reason for wanting to analyse oxygen but I’ll explain more when I write my ‘explainer’ blog. There are quite a few authors involved in this work, based across Europe and the USA, so it’s been a tricky project to manage in terms of time zones and opinions, but we got there in the end, particularly after a huge amount of detailed lab work by some of my co-authors (thank you Richard!). It’s so nice to finally see the paper out for the community to read, hopefully they like it!
