Confirmed carcinogen. When heated to decomposition it emits toxic vapors of SOx and Ni.
DG0875000
It is known from few ultramafic intrusions within terrestrial rocks. The Honeymoon Well ultramafic intrusive, Western Australia is known to contain heazlewoodite-millerite sulfide assemblages within serpentinized olivine adcumulate dunite, formed from the metamorphic process.
Heazlewoodite (CAS NO.12035-71-1) can be used in producing of Sulphur and Nickel .
It is formed within terrestrial rocks by metamorphism of peridotite and dunite via a process of nucleation and only formed via metamorphic exsolution of sulfur from the lattice of metamorphic olivine.
