Scientific paper

Geochemical and Sm-Nd isotopic data are presented on the sediments and their potential source rocks from the Late Proterozoic-Cambrian Adelaide Fold Belt in southern Australia. The data indicate that the Archean to Mid-Proterozoic basement rocks of the Gawler Craton in southern Australia record a history of additions from the contemporary depleted mantle, some of which assimilated preexisting crust. The chemical and isotopic data are consistent with a mode in which deformation and subsequent rapid exhumation during the Delamerian Orogeny provided the source for the thick Ordovician-Silurian flysch in the Lachlan Fold Belt to the east. While the data indicate a model of regional, intracontinental additions via advection of mantle melts accompanied by assimilation of preexisting crustal materials, they do not support a model of purely intracrustal recycling.
