In numerous examples of thermally and tectonically overprinted gold-bearing "sheeted" quartz veins of the Callie gold mine/deposit, Tanami, Northern Territory, Australia, native gold is locallised in late-stage, variably penetrative fracturing/microfracturing cross-cutting the plastically deformed apaitite, xenotime, tourmaline and sulphide bearing, chlorite and alkali feldspar-rich quartz veining. The native gold intergrown with carbonate and quartz fills microfractures in brittle deformed and recrystallised tourmaline of the early vein assemblage, and is localised as inclusion trails within recrystallised quartz together with late-stage aqueous, liquid-rich fluid inclusions.
