Orange Wulfenite Crystals on Matrix - Mexico

This specimen contains blocky, orange wulfenite crystals, protruding from matrix containing small traces of mimetite in the matrix, collected from the Qjuela Mine in Mapimi, Mexico. Some bi-pyramidal wulfenite crystals can be found as well.

This specimen comes with an acrylic display stand.

Mimetite is a lead chloro-arsenate mineral with the chemical formula of Pb5(AsO4)3Cl. Depending on conditions during formation/replacement, arsenate radicals (As04) can be replaced by a phosphate (PO4) or vanadate (VO4) radical. This alteration is what leads to the formation of pyromorphite and vanadinite, hence why they are typically found associated with each other. Often red to yellow in color, mimetite can occur in a variety of structures, from small prismatic clusters and crusts to incredible hexagonal crystals both thick and thin.
