Anglesite

PbSO4

Anglesite is a sulfate mineral prized by collectors for its exceptional color range, with several world-class Chinese localities.

Pseudomorph Relationships
Replaces — this mineral is often a pseudomorph after:
← Galena replacement
Anglesite (PbSO₄) coats galena in sulfate-rich environments.
Cornwall; Italy.
A pseudomorph (Greek "false form") is a mineral with the external shape of another species — the chemistry has changed but the crystal habit is inherited.

TL;DR · 1 min read
Anglesite (PbSO₄) is the secondary lead sulfate of the oxidized cap zones of galena-bearing Pb-Zn deposits. Named after Anglesey (Wales) where it was first described, Anglesite is famous for adamantine transparent crystals from Touissit (Morocco), Tsumeb (Namibia), and Sardinia.

Anglesite (PbSO₄) is the secondary lead sulfate of the oxidized cap zones of galena-bearing Pb-Zn deposits. Named after Anglesey (Wales) where it was first described, Anglesite is famous for adamantine transparent crystals from Touissit (Morocco), Tsumeb (Namibia), and Sardinia. It forms by oxidation of galena, often as paramorphic pseudomorphs preserving galena cube outlines.
