The blodite group (or Blödite group) is a group of minerals with two (in most cases divalent) cations and two anions. The group includes

blödite Blödite or bloedite is a hydrated sodium magnesium sulfate mineral with the formula Na2Mg(SO4)2·4H2O. The mineral is clear to yellow in color often darkened by inclusions and forms monoclinic crystals. Blödite was first described in 1821 for ...

Na₂Mg(SO₄)₂•4H₂O,

leonite Leonite is a hydrated double sulfate of magnesium and potassium. It has the formula K2SO4·MgSO4·4H2O. The mineral was named after Leo Strippelmann, who was director of the salt works at Westeregeln in Germany. The mineral is part of the blodite ...

K₂Mg(SO₄)₂•4(H₂O), anapaite Ca₂Fe(PO₄)₂•4(H₂O), schertelite (NH₄)₂Mg(PO₃OH)₂•4(H₂O,)

manganoblödite Manganoblödite is a 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 relativ ...

Na₂Mn(SO₄)₂•4(H₂O),

cobaltoblödite Cobaltoblödite is a rare cobalt mineral with the formula Na2Co(SO4)2·4H2O. Cobaltoblödite was found in the Blue Lizard mine, San Juan County, Utah, USA, which is known for secondary uranium minerals. Cobaltoblödite occurs intimately intergrown ...

Na₂Co(SO₄) ₂•4(H₂O),

changoite Changoite is a rare zinc sulfate mineral with the formula Na2Zn(SO4)2·4H2O. Chagoite was discovered in the San Francisco Mine near Sierra Gorda, Antofagasta, Chile. The mineral is a zinc-analogue of blödite, cobaltoblödite, manganoblödite and ...

Na₂Zn(SO₄)₂•4(H₂O)
