GeoPT reports for Round 47/47A now available for download

The reports for Rounds 47 and 47A are now available for download, so that participants can respond, if necessary, to any unexpected evidence of questionable performance before embarking on Round 48 of GeoPT, involving the monzonite, MzBP-1.

We are pleased to report that over 90 laboratories contributed to Round 47/47A, which is very welcome, given the global situation that has prevailed during 2020.

The data submission window for GeoPT48 will open on the 25th January 2021 with the reporting deadline for MzBP-1 of 24th March.
