This page is currently not sponsored. Click here to sponsor this page.
Formula:
Mn10As6O18(OH)Cl
formula is very tentative
Specific Gravity:
4.49
Crystal System:
Tetragonal
Probably related to magnussonite. Originally reported by Moore (1969) (reference not reported in the information-publishing paper).


Occurs in a low-grade ore comprising calcite, jacobsite, and manganoan clinohumite, that also contains katoptrite and manganhumite.
