A-Team Quarterly Update – Third Quarter 2020

It has been an important quarter with several important manuscripts moving forwards into the public domain. It has seen the publication of major papers by Anouk Borst and Will Hutchison as well as EPSRC grant success for Nicky Horsburgh. This has been a particularly productive time for Tim Kinnaird, whose research group focussing on landscape dynamics determined from mineral luminescence dating, has received national and international recognition in the press for their work on Stonehenge.

With lockdown in the UK, our visits and conference presentations have been curtailed but we look forwards to completing these once travel restrictions are lifted.

Models of equilibrium fractionation of sulfur isotopes between sulfide and sulfate in alkaline igneous deposits (a–c) compared to data from natural systems (d–f). The data show large variations in redox as a function of temperature in alkaline igneous fluid systems (see Hutchison et al. (2020) for a fuller description).

Media

The research group has had a lot of publicity for its work over the last quarter. Tim Kinnaird’s group has been interviewed for its research at Stonehenge, Anouk Borst’s paper on Ion Adsorption Clays was picked up by the Rare Earth Industries Association (REIA) the Diamond Synchrotron and Physics.org whereas Nicky Horsburgh’s PhD results were covered by REIA and Ancient TL.

Outreach

Nicky Horsburgh has been working for the GeoBUS project for the last months and put together a series of outreach events. This has included a short fieldtrip by Adrian on “Ancient Volcanoes and Elie Rubies” which will take place on Sunday 11 Oct 2020.
