Manganoblödite is a rare manganese mineral with the formula Na2Mn(SO4)2·4H2O.
[5] Manganoblödite was found in the Blue Lizard mine, San Juan County, Utah, US, which is known for several relatively new secondary uranium minerals[6] In the mine, manganoblödite occurs intimately intergrown with manganese-, cobalt- and nickel-enriched blödite and a yet another new mineral - cobaltoblödite.
It is also analogous to changoite, cobaltoblödite and nickelblödite - all three are members of the blödite group.
[4] Manganoblödite is impure, containing admixtures of magnesium, cobalt and nickel.
[3] Besides blödite and cobaltoblödite, other minerals associated with manganoblödite include chalcanthite, gypsum, johannite, sideronatrite, a feldspar group mineral and quartz.
