Abstract

Zircon geochronology confirms the Errabiddy Shear Zone as a major structural boundary separating two distinct geological terranes within the southern part of the Palaeoproterozoic Capricorn Orogen of Western Australia. Rocks on the south side of the Errabiddy Shear Zone represent parts of the Archaean Yilgarn Craton that were variably reworked during the c. 2.0 Ga Glenburgh and c. 1.8 Ga Capricorn orogenies. Rocks on the north side represent an exotic terrane (the 'Glenburgh Terrane') comprising c. 2500 Ma (and possibly older) gneisses which evidently record tectonothermal activity c. 2390 Ma, and which, together with quartzitic metasedimentary units deposited after c. 2270 Ma, collided with the Yilgarn Craton during the Glenburgh orogeny. Regional deformation, high-grade metamorphism and voluminous felsic plutonism occurred throughout the complex in association with both the Glenburgh and Capricorn orogenies. (C) 2003 Elsevier B.V.
