Abstract
The Wild Wave granodiorite is intrusive into the Cambro-Ordovician Girilambone group and is nonconformably overlain by the Meryula formation of Early Devonian age. It gives a biotite Rb/Sr age of 418 + or - 2 m.y. and an initial 87Sr/86Sr ratio of 0.7051 + or - 0.0002. The magma is inferred to have been derived from mafic rocks in the lower crust.-N.C.N.S.
