Practicals:
There will be a total of four practicals, which will take place every day at 14.30–17.00 (CEST) in separate rooms (both on-site and online). Participants will be split in four groups and each group will attend one practical per day. Practicals will be supervised by a number of trainers and will include a number of exercises. Participants on-site will have to bring their own laptops and all participants will have to install any required software in advance before the School. Instructions, software and data files of the exercises will be provided by August 29th.
The list of practicals is:
- Practical 1: Data processing in Mössbauer spectroscopy (C. McCammon, V. Cerantola)
- Practical 2: Data processing in XANES spectroscopy (L. Cottrell, A. Berry, G. Yaxley)
- Practical 3: Redox phase equilibria in mantle and crustal rocks (E. Green, V. Stagno, S. Schorn)
- Practical 4: Redox evolution of degassing magmas (R. Moretti)

Participants' presentations (Poster):
Poster sessions will take place on September 6th, 7th and 8th, between 17.00 and 18.30 (CEST). On-site and online posters will be avaialble for visualization every day.
During the poster sessions, online presenters should be available in their own 'Booths' of the 'Expo' section of the Zoom Event platform used for the School. If a presenter will not be present, this might also be because of time zones of participants. Presenters might be contacted also using the chat or email.
Each on-site presenter will be available for two days in the on-site area dedicated to posters and for one day she/he should be available also online. See the list below for details.
