- 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.

Thank you for the presentation. You mention that there are enrichment in Cu, P, V and Ag. How enriched are they (~ppm) and in what minerals are these elements held? Do they form their own minerals or are they found as accessory elements in other minerals?
Is your hydrothermal manganese (probably modern) oxide precipitate of different chemistry or mineralogy from other preported precipitates, or close to those reported elsewhere in the active areas?
What is the scale of these hydrothermal deposits? Is all of the Mn mineralization on the smaller mm-cm scale as replacement or precipitation in the other various rock types? Or are there hand-sized or larger pieces of hydrothermal Mn?
Is there any spatial relationship between the precipitation of the Mn oxide minerals and distance from the ridge?
