- Name
- Sublimation residue made of mineral mixture (Magnetite 63wt%, NH4-nontronite 22wt%, Antigorite 9wt%, Dolomite 6wt%) at 173 K
- Comments
- The sample resulting from the sublimation experiment has been carefully taken out of the cell, and cut to adjust to the size of the sample holder. Maximum care was taken to keep the physical structure of the sample.
