Austinite is a member of the adelite-descloizite group and has the chemical formula CaZn(AsO4)(OH). It forms in oxidized arsenic-rich metal deposits and is often associated with adamite, limonite, talmessite and quartz. It often exhibits a greenish coloration, though it has also been known to occur as yellow, brown, white and yellow-white aggregations. Austinite has been collected from the United States, Mexico, Australia, Bolivia, Namibia and several other locations.

Austinite was named after Austin Flint Rodgers, an American mineralogist at Stanford University.
