Sign in to saveAlso known as Bukovskyite, IMA1967-022
Bukovskyite (also known as "clay of Kutná Hora") is an iron arsenate sulfate mineral with formula: Fe2(AsO4)(SO4)(OH)·7H2O which forms nodules with a reniform (kidney-shaped) surface. Under a microscope, these nodules appear as a collection of minute needles similar to gypsum. Some can be seen with the naked eye and occur inside the nodules.

Bukovskyite (also known as "clay of Kutná Hora") is an iron arsenate sulfate mineral with formula: Fe2(AsO4)(SO4)(OH)·7H2O which forms nodules with a reniform (kidney-shaped) surface. Under a microscope, these nodules appear as a collection of minute needles similar to gypsum. Some can be seen with the naked eye and occur inside the nodules.
Bukovskyite was first described from pit heaps from the Middle Ages, where sulfate ores had been mined at Kank, north of Kutná Hora in Bohemia, Czech Republic, and other old deposits in the vicinity. Only recently defined and acknowledged, it was approved by the IMA in 1969.
