Meisserite
Meisserite is a very rare uranium mineral with the formula Na(UO)(SO)(SOOH)(HO). It is interesting in being a natural uranyl salt with hydrosulfate ( hydroxysulfate) anion, a feature shared with belakovskiite. Other chemically related minerals include fermiite, oppenheimerite, natrozippeite and plášilite. Most of these uranyl sulfate minerals was originally found in the Blue Lizard mine, San Juan County, Utah, USA.The mineral is named after Swiss mineralogist Nicolas Meisser.
