| Species: | 'Obertiite Root Name Group' (not an IMA approved species) |
| Formula: | ANa2(Z32+Z3+Ti)Si8O22O2 |
| Comments: | Oberti et al. (2017) have identified ferri-obertiite from Rothenberg. So far mangani-obertiite has not been identified from here, but it is very difficult to differentiate between the two minerals without identifying both the Mn3+/Mn2+ and Fe3+/Fe2+. |
