GeoPT Autumn Round 2019

For the Autumn Round we had a granodiorite as our routine test material. We also provided as a supplementary test material, a phosphate rock that was intended to be more challenging for analysts. The data submission deadline was Wednesday 11th December.

We expect to provide reports for download by the end of January 2020.
