Millosevichite
Encyclopedia
Millosevichite is a rare mineral with the chemical formula Al2(SO4)3. Aluminium
is often substituted by iron
. It forms white to yellowish cryptocrystalline
, often porous, masses. The mineral is mainly known from burning coal dumps, acting as one of the main minerals forming sulfate crust
. It can be also found in volcanic
environments.
Aluminium
Aluminium or aluminum is a silvery white member of the boron group of chemical elements. It has the symbol Al, and its atomic number is 13. It is not soluble in water under normal circumstances....

Cryptocrystalline
Cryptocrystalline is a rock texture made up of such minute crystals that its crystalline nature is only vaguely revealed even microscopically in thin section by transmitted polarized light. Among the sedimentary rocks, chert and flint are cryptocrystalline. Carbonado, a form of diamond, is also...

Sulfate crust
Suasdlsdjety godovikovite and millosevichite. The outer zone can easily be hydrated giving rise to minerals like tschermigite and alunogen. The zone forms due to interaction with hot coal-derived gases with the "sterile" material Suasdlsdjety godovikovite and millosevichite. The outer zone can...
