- Sponsor Seminars
These are scheduled events to help delegates test out the tools and platform we will be using for the Q&A and other events at the conference.
Our workshop program provides training and teaching in topics across geochemistry and related fields. We are currently liaising with the workshop organisers to ascertain if any workshops can become virtual. Any updates will be added to this page.

Do you control on the amount of common Pb (via 204Pb) from core to rim in your apatites? In micas, we repeatedly see an increase in common Sr towards the rim- some sort of in-diffusion. I would be interested to know 1) just to see if it is a common feature and 2) as it may influence your age calculations if the fluid (I suppose some sort of fluid would be required) has variable Pb isotope composition, like release from other radiogenic phases.
Hi Dave, excellent talk. Do you thinking resigning all low grade apatite to be low U and therefore undatable is realistic? In some low-grade pelitic rocks (with perhaps low Fe3+) apatite can form in the absence of epidote or even allanite, potentially allowing it to take in U. Do you think it is worth exploring more low-grade terranes to investigate the full potential of apatite U-Pb?
