Emplacement and deformation ages of the Wyangala Granite, Cowra, NSW
New geochronological data from the Wyangala Granite in the Hill End Trough, Eastern Lachlan Fold Belt, constrain the timing of granite emplacement and subsequent deformation. SHRIMP U-Pb dating of zircon indicates that the granite crystallised in the late Silurian (425.2 ± 3.5 Ma). Subsequent west-over-east thrusting resulted in the development of mylonite along its eastern margin and cataclasis of megacrystic and groundmass feldspars, especially in pervasive shear zones within the granite....[Show more]
