This has been attributed to the cooling of the earth’s mantle with time.

The Jinchuan deposit, China,5. However, the intrusive rocks that host the sulfide ores are all ultramafic, ranging from dunite to olivine pyroxenite, and, previously, had been thought to have formed from an ultramafic magma with an MgO content of >30 wt% (S.G.U. 1984); this is quite different to the general features of other Cu and PGE rich Ni sulfide deposits.
