TitleMillerite with hematite and magnetite
DescriptionMost of this small sample (7 cm across) is red-brown hematite, but if you look closely at an enlarged photo you can find some needles of millerite, NiS (nickel sulfide). Millerite is one of a few sulfide minerals that form fine acicular crystals that appear as hair-like fibers aggregated into sprays. The specimen also contains small amounts of black magnetite (althouth it is difficult to see) and minor quartz.
