New geochemical and isotopic data for volcanic and shallow-level intrusive rocks of the Murchison Domain in the Youanmi Terrane of the Yilgarn Craton help to clarify some of the stratigraphic ambiguities in the area and are consistent with the most recent lithostratigraphic model. The results ...

The presence of well-preserved boninites in the Polelle Group indicates a significant role for subduction tectonics during the 2825–2700 Ma evolution of the Youanmi Terrane. The subduction zone is tentatively linked to the accretionary processes proposed along the Youanmi Terrane–Narryer Terrane ...
Youanmi TerraneNew studies in the central and southern parts of the Murchison Domain in the Youanmi Terrane, western Yilgarn Craton, reveal previously unidentified igneous rock types in addition to boninitic occurrences similar to those found in the northern part of the domain. New results also ...
The ages, P–T conditions, and high apparent thermal gradients from the study area suggest metamorphism occurred as the result of high heat flow into thinned crust of the Youanmi Terrane and indicates a complex thermal history within this region of the Yilgarn Craton. These results are ...
The general crustal structure of the Youanmi Terrane-a tectonic unit within the Neoarchean Yilgarn Craton-and its relationship to ore deposits are of major interest in Western Australia. To image geological structures, the Geological Survey of Western Australia in collaboration with Geoscience Australia...

In the Yilgarn Craton, the Mougooderra Formation is an extensive sedimentary sequence that preserves low-variance metamorphic mineral assemblages and unconformably overlies older greenstone sequences within the Youanmi Terrane. Here we present garnet Lu-Hf and Sm-Nd geochronology in combination with ...
The South West and Youanmi Terranes in the western Yilgarn Craton contain quartz-rich metasedimentary rocks, similar in character to those at Mount Narryer and Jack Hills in the Narryer Terrane, with abundant detrital zircons back to c. 3800 Ma, and rare detrital zircons as old as c. ...
