Pyrite framboids have been recognized in fumaroles on Deception Island, Antarctica. The sulphide was deposited around reworked pyroclastic tephra (lapilli). The formation process starts as a reaction between glass and hydrogen sulphide, giving rise to nucleation and growth of iron monosulfide microc...
