TitleAustinite with adamite on limonite
DescriptionAustinite, CaZnAsO4OH (calcium zinc arsenate hydroxide), is a fairly rare, but popular collection mineral. It forms in the oxidation zone of zinc ore deposits and often with the sometimes similar looking adamite. It can have a very nice color and silky or sub-adamantine (almost gem-like) luster. Both appear here on limonite.
LocationUSA ▹ Utah. Near Gold Hill.
