Many forms of sulfur are found on Kīlauea Volcano
Detailed Description
Continued degassing from fumaroles at fissures on Kīlauea Volcano's lower East Rift Zone produce native sulfur crystals when sulfur dioxide and hydrogen sulfide gases react and cool upon reaching the surface. The delicate sulfur crystals are 5–15 mm (0.2–0.6 in) long. USGS photos by A. Lerner, 2018.
