Title | Pyromorphite from Coeur d'Alene, Idaho |
Description | Pyromorphite (green mineral) is a lead chlorophoshpate, Pb5(PO4)3Cl. It forms a chemical series with two other minerals: mimetite (Pb5(AsO4)3Cl) and vanadinite (Pb5(VO4)3Cl). Pyromorphite is usually green, mimetite is usually yellow, and vanadinite is usually red, but distinguishing these minerals by color is sometimes misleading. Pyromorphite sometimes has a distinguishing crystal habit of stacked barrel shaped crystals that branch out in a way that is reminescent of some branching cactus varieties. Pyromorphite has the same atomic arangement as apatite and therefore crystals of the two may have similar shapes. |
