Small volcanic island with very high temperature fumaroles (up to 945°C, Matsuo et al. 1974). Rhyolite leached out by acid fumaroles was mined for silica (up to 97% SiO2). Fumarole gases here have the highest content of molybdenum vapour (1 ppm) and gold vapour (32 ppb) of any volcano (Hedenquist et al. 1994).
(Note: This is NOT the same Iwo-jima that became famous in WW2 - See under Tokyo Prefecture.)

Detailed Mineral List:

Aegirine
Formula: NaFe3+Si2O6
Description: Green to dark-green elongated, sometimes acicular crystals of good luster and well-developed crystal tips. Common in high-temperature fumaroles in the vicinity of halite crystals, in the hotter, central parts of the fumaroles.
