Manganoblödite is a very rare manganese mineral with the formula Na2Mn(SO4)2•4H2O. Somewhat chemically similar mineral is D'Ansite-(Mn) Manganoblödite was found in the Blue Lizard mine, San Juan County, Utah, US, which is known for several relatively new secondary uranium minerals In the mine, manganoblödite occurs intimately intergrown with manganese-, cobalt- and nickel-enriched blödite and a yet another new mineral - cobaltoblödite. Manganoblödite, as suggested by its name is a manganese-analogue of blödite. It is also analogous to changoite, cobaltoblödite and nickelblödite - all three are members of the blödite group.
Association and origin
Besite blödite and cobaltoblödite, other minerals associated with manganoblödite include chalcanthite, gypsum, johannite, sideronatrite, a feldspar group mineral and quartz.
