Jarosite is a common mineral in acidic, sulfate-rich environments where it can regulate acidity and capture toxic metals. This research examined jarosite-bearing outcrops in Victoria, Australia, to better understand jarosite formation and behaviour which is critical for its management. Geochemistry and crystal structure analysis showed that jarosite formation in acid-sulfate environments involves an interplay of chemical processes that, together with jarosite recrystallisation and environmental interactions, results in jarosite having chemical and structural complexity. Thorough characterisation of jarosite in acid-sulfate environments is therefore crucial to manage them in these environments successfully.
