Mimetite
Mimetite is a lead arsenate chloride mineral (Pb5(AsO4)3Cl) which forms as a secondary mineral in lead deposits, usually by the oxidation of galena and arsenopyrite. The name derives from the Greek Μιμητής (mimetes), meaning "imitator," and refers to mimetite's resemblance to the similar mineral pyromorphite. This focus-stacked photograph shows a 3 cm × 1.7 cm × 1 cm (1.18 in × 0.67 in × 0.39 in) sample of mimetite collected from the Congreso-León mines in the Mexican state of Chihuahua.Photograph credit: Ivar Leidus
