Both sulphide Bushveld (South Africa) and laterite nickel deposits are shown. Data are from Geoscience Australia’s OZMIN and MINLOC resource databases. 2100 Turee Creek Event ME 3 (m) ~2210 Ma Proterozoic Large Igneous Provinces (LIPs) Dashed lines indicate the geographic extent of five Magmatic Events distinguished as 2300 exceptionally large emplacements of dominantly mafic magma. Those shown on this map are expressed only by time-equivalence of intrusion and extrusion: cogenetic magmatism across crustal provinces is not necessarily implied. Colours and unit polygons are linked to ME 2: Jimberlana, WA – Ni-Cu sulphides Widgiemooltha Event ME 2 (mu) ~2420 Ma the 1:5 000 000 Map on Sheet 1, and to the Time–Space–Event Chart. The approximate Weeli Wolli Event ME 1 (mu) ~2455 Ma Penikat (Finland) eastern limit of Precambrian crustal elements is shown as the Tasman Line. 2500 Kalkarindji LIP: ME 30 ~520 Ma. Extensive preservation of basalt lavas across the North Australian Craton and central Australia; intrusions in the Kimberley and Irindina provinces.
