Eztlite
Eztlite is an IMA-recognized mineral species in the sulfate class, with the chemical formula Pb₂Fe³⁺₃(Te⁴⁺O₃)₃(SO₄)O₂Cl.
It crystallizes in the monoclinic crystal system.
Key properties: Mohs hardness 3; specific gravity 4.5; Orange streak; optically biaxial.
IMA symbol Ez, IMA status: approved, named in 1980.
Very rare in oxidized ore in a matrix of intensely silicified and brecciated rhyolite vitrophyre cemented by drusy quartz and carrying pyrite and tellurides.
It is found associated with Cuzticite, emmonsite, schmitterite, kuranakhite, pyrite.
The name comes from the Nahua language for blood, in allusion to the color.
