(2006) | 10.1016/j.oregeorev.2006.05.002 | OGR29_177 | See Table. 1 Global resources of nickel metal and ages of the major nickel sulfide deposits of the world. Age can refer to the age of a specific nickel sulfide deposit, or the general age of the metallogenic province containing nickel deposits that are similar to a dated deposit (e.g. 2705 Ma Komatiite-hosted deposits in the Eastern Goldfields Province). Dates on felsic volcanic rocks that include komatiites are consistent with an inferred eruption age for these komatiites of c. 2705 Ma. |
