- Orogenic gold (Archaean greenstone belt)
Laverton greenstone belt (north-eastern Eastern Goldfields Province, Yilgarn Craton), greenschist-facies metamorphism. Orogenic gold dated at about 2.65 Ga across the district (hydrothermal monazite and xenotime, SHRIMP U-Pb), unrelated in age to nearby granitoids: a single fluid from a deep, distal source according to the authors; regional fluid calculated at 300 °C at δ13C -3.9 ‰ and δ18O +5.8 ‰. Gently east-dipping basalt flows, cut by the Western shear zone and by quartz-feldspar porphyry dykes (mafic suite) with chlorite-magnetite alteration; syn-D3 gold in stacked shear zones and tension veins, with carbonate-sericite-pyrite-silica-fuchsite alteration. Monazite and xenotime dated at 2649 ± 11 Ma. Coordinates not given.
