Iron-nickel-copper sulfides occur as micrometer-sized subspherical blebs in glass inclusions within olivine phenocrysts and in glass within quenched groundmass. Bulk sulfides in the eruption pumice are enriched in Ni relative to Cu. The same species, plus chalcopyrite, are present in the Kilauea Iki lava lake, but the bulk sulfides are markedly enriched in Cu relative to Ni.
