G-Chron 2019 — Zircon Rak-17: Report now available for download

The download procedure was detailed in a global email sent to all participants on 10th April. If you did not receive that email, check your junk/spam traps.

The aim for 2020 was to send out the test material for Round 2 during September. Owing to the Coronavirus pandemic there is likely to be some slippage in the schedule. It is hoped that the zircon will be accompanied by a titanite.
