Adanite

Adanite is an IMA-recognized mineral species in the sulfate class, with the chemical formula Pb₂(Te⁴⁺O₃)(SO₄).

It crystallizes in the monoclinic crystal system (space group P2_1/n).

Key properties: Mohs hardness 2.5; specific gravity 6.595; White streak; Adamantine luster; optically biaxial.

IMA symbol Adn, IMA status: approved, named in 2019.

Secondary in the oxidation zone of a polymetallic (Au-Ag-Cu-Pb) hydrothermal vein deposit (Tintic).

It is found associated with Anglesite, azurite, chrysocolla, fluorapatite, northstarite, plumbogummite, tellurite, zincospiroffite (Tintic); jarosite, frohbergite.

The mineral was named to honor American mineral collector and micromounter Charles (Chuck) Adan (b. 1961) of Salt Lake City, Utah. Mr. Adan discovered the studied samples of pararaisaite.
