- 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 your interesting presentation. We want to prioritize questions from the audience over the questions from the conveners, but if there is time and no other questions, please feel free to address these questions.] 1) In one of the slides about the reaction-transport models, it was mentioned that hematite and oxidized minerals would be more abundant at depth than at the surface. Why is that? If the source of water was from the surface, wouldn't the rock layers at depth remain more reduced? 2) Would the modeled mineralogy results change significantly if the source of water was groundwater and not surface weathering? 3) The model that matches the observations closest is the one with acidic pH and increasing temperature with depth. Does the acidic pH of the fluid have any implications for the atmospheric pCO2 content? Does the pH neutralize and change with depth? Also, if I interpreted the graphs correctly, the temperature increases from 1 C to 75 C in about 15 m. Isn't that a steep temperature gradient? Thank you! Mohit
