TitleArsenopyrite from Erythrite Mine, Middletown, Conneticuit
DescriptionThe white mineral is quartz, and the gray mineral is arsenopyrite, FeAsS (iron arsenic sulfide). Arsenopyrite is often bright metallic and silvery but is rather drab in this specimen (8 cm across). It is the most common mineral that contains arsenic, and is thus a major ore of that element. It is also sometimes mined because it may contain gold. Arsenopyrite has a distinctive garlic odor when struck; miners like that smell because it means that gold ore may be nearby.
