Poughite
Poughite is an IMA-recognized mineral species in the sulfate class, with the chemical formula Fe³⁺₂(Te⁴⁺O₃)₂(SO₄)·3H₂O.
It crystallizes in the orthorhombic crystal system (space group P2_1nb).
Key properties: Mohs hardness 2.5; specific gravity 3.758; optically biaxial.
IMA symbol Pgh, IMA status: approved, named in 1966.
An alteration product of pyrite in the oxidized zone of a hydrothermal Au–Te deposit (Moctezuma mine, Mexico).
It is found associated with Pyrite, emmonsite, jarosite, “limonite”, quartz (Moctezuma mine, Mexico); mandarinoite (El Plomo mine, Honduras).
The mineral was named to honor Dr. Frederick Harvey Pough (1906–), Reno, Nevada, USA, American mineralogist and gemmologist, for his numerous contributions to these sciences.
