On Tuesday April 17, we had the great pleasure of giving a lab tour to Sir David Attenborough, who was the guest of honour at the Kathleen Lonsdale Building reopening ceremony. After a brief introduction to U-Pb, U-Th-He and K-Ar geochronology, our esteemed guest asked the pertinent question as to whether these chronometers could be cross-calibrated. Interestingly, improving such cross calibrations turns out to be one of our top priorities for the coming years! Further information about Sir David's visit to the Department can be found here. |
