...Anthony J. Crawford; Mark G. Doyle Abstract The Tropicana gold deposit (7.9 Moz) is hosted by the Neoarchean, amphibolite- to granulite-grade Tropicana Gneiss. These rocks form part of the Plumridge terrane, a tectonic unit that separates the in situ eastern margin of the Yilgarn craton from...

... Ga. The timing of the Tropicana mineralization is distinctly younger than greenstone-associated gold deposits elsewhere in the Yilgarn craton. As in the Dharwar craton, India, and the Limpopo belt, Zimbabwe, economic gold mineralization at Tropicana postdates the major peak of Late Archean world...

...-and-thrust belt above the flat-lying Plumridge Detachment. This fold-and-thrust belt is host to the c. 2520 Ma, Tropicana gold deposit. The Plumridge Detachment may extend north to the Yamarna greenstone belt, linking to the Yamarna Shear Zone – the boundary between the Burtville and Yamarna Terranes...
