Formula: CaF2
β“˜ Galena
Formula: PbS
β“˜ Magnetite
Formula: Fe2+Fe3+2O4
Habit: massive
Colour: black
Fluorescence: No
Description: Black metalic masses. Some oktahedral faces are visible. A magnet sticks on it.
β“˜ Nickeline
Formula: NiAs
β“˜ Nickelskutterudite
Formula: (Ni,Co,Fe)As3
β“˜ Parasymplesite
Formula: Fe2+3(AsO4)2 · 8H2O
