2" Botryoidal Yellow Mimetite - La Morita Mine, Mexico

These are botryoidal, yellow mimetite formation on matrix, collected from the La Morita Mine in Chihuahua, Mexico. The wulfenite crystals exhibit a wonderful silky luster. The entire specimen measures 2 x 1.3".

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're typically found associated with each other. Regularly ranging between red and 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.
