Common questions

What is Pyromorphite?

Lead phosphate chloride forming bright green barrel-shaped hexagonal crystals. An important secondary lead mineral.

How can you identify Pyromorphite?

Compare several properties rather than relying on colour alone. This entry records colour: Green, brown, yellow, orange; lustre: Resinous to adamantine; streak: White; Mohs hardness: 3.5-4; cleavage: Poor; crystal system: Hexagonal; transparency: Translucent to opaque. Confirm an important identification with additional field tests or qualified laboratory work.

How does Pyromorphite form?

Forms in the oxidation zone of lead ore deposits by reaction of phosphate-bearing solutions with galena.

Where is Pyromorphite commonly found?

Germany, China, France, USA; found in oxidized lead deposits.

What is Pyromorphite commonly confused with?

Pyromorphite may be confused with Mimetite, Vanadinite, Apatite. Compare multiple diagnostic properties because colour and surface appearance can overlap.
