Blödite Group
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 Na2Mg(SO4)2•4H2O, leonite K2Mg(SO4)2•4(H2O), anapaite Ca2Fe(PO4)2•4(H2O), schertelite (NH4)2Mg(PO3OH)2•4(H2O,) manganoblödite Na2Mn(SO4)2•4(H2O), cobaltoblödite Na2Co(SO4) 2•4(H2O), changoite Changoite is a rare zinc sulfate mineral with the formula Na2Zn(SO4)2·4H2O.

Blödite
Blödite or bloedite is a hydrated sodium magnesium sulfate mineral with 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 an occurrence in a salt deposit in Ischler Salzberg, Bad Ischl, Gmunden, Austria and named for German mineralogist and chemist Karl August Blöde (1773–1820). It is found worldwide in evaporite, evaporitic Sedimentary depositional environment, sedimentary environments such as the Great Salt Lake, Utah.

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 group of hydrated double sulfate minerals. Properties Leonite has a bitter taste. When leonite is analyzed for elements, it is usually contaminated with sodium and chloride ions, as it commonly occurs with sodium chloride. Crystal structure In the mineral family of leonite, the lattice contains sulfate tetrahedrons, a divalent element in an octahedral position surrounded by oxygen, and water and univalent metal (potassium) linking these other components together. One sulfate group is disordered at room temperature. The disordered sulfate becomes fixed in position as temperature is lowered. The crystal form also changes at lower temperatures, so two other crystalline forms of leonite exist at lower temperatures. The divalent meta ...

Anapaite
Anapaite is a calcium–iron phosphate mineral with formula: Ca2Fe2+(PO4)2·4H2O. It is a mineral that typically occurs in cavities in fossil bearing sedimentary rocks. It is also found in phosphate bearing iron ores and rarely in pegmatites. It is commonly found with goethite, siderite and vivianite. It was named after the type locality on the Black Sea coastal region of Anapa, Taman Peninsula, Russia. Noted localities include Kertch (Crimea, Ukraine), Bellver de Cerdanya (Lleida, Catalonia, Spain , image_flag = Bandera de España.svg , image_coat = Escudo de España (mazonado).svg , national_motto = ''Plus ultra'' (Latin)(English: "Further Beyond") , national_anthem = (English: "Royal March") , i ...) and Valdarno, Tuscany, Italy.

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 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. Notes on chemistry Manganoblödite is impure, containing admixtures of magnesium, cobalt and nickel. Association and origin Besides blödite and cobaltoblödite, other minerals associated with manganoblödite include chalcanthite, gypsum, johannite, sideronatrite, a feldspar group mineral and quartz Quartz is a hard, crystalline mineral composed ...

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 with manganese-, cobalt- and nickel-enriched blödite and a yet another new mineral - manganoblödite. Cobaltoblödite, as suggested by its name is a cobalt-analogue of blödite. It is also analogous to changoite, manganoblödite and nickelblödite - other members of the blödite group. Notes on chemistry Manganoblödite is impure, containing admixtures of magnesium, manganese and nickel. Association and origin Besite blödite and cobaltoblödite, other minerals associated with manganoblödite include chalcanthite, gypsum, johannite, sideronatrite, a feldspar group-mineral and quartz Quartz is a hard, crystalline mineral composed of silica (silicon dioxide).

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 nickelblödite - other representatives of the blödite group. In terms of chemistry changoite is somewhat similar to gordaite. The mineral's name comes from the early inhabitants of Chile - Changos. Traces of magnesium and calcium in changoite are negligible. Minerals associating with changoite are gypsum, zinc Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodi ...-bearing paratacamite, and thénardite.
