- 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.

Interesting talk. How low of a temperature is envisioned for the secondary weathering dissolution-reprecipitation of apatite? Are there any experimental data that exist to support this scenario? Any thermometry available for these samples for the different apatite zones, such as inclusions of other minerals that can yield temperature information, or O isotopes for mineral pairs (e.g. apatite, rutile?).
Thanks Kathryn, in all honesty, temperature isn't a criterion I'd considered as I'd imagine it's 'ambient conditions'. However, I admit that this is pretty broad, and you have started me wondering if we can borrow the apatite O isotope thermometer from the palaeo community and apply it in this scenario, or even clumped isotope thermometry on the carbonate component of the apatite? This would be an interesting avenue to explore.
