Osmium Isotopic Evidence for Crust-Mantle Interaction in the Genesis of Continental Intraplate Basalts from the Newer Volcanics Province, Southeastern Australia

Basalts from the Quaternary Newer Volcanics Province in southeasternAustralia have a large diversity in their chemical and Nd, Srand Os isotopic compositions. Plains series olivine tholeiitesand Cones series nepheline hawaiites have distinctive isotopiccompositions and are clearly not related to each other by asimple genetic process. The Cones series nepheline hawaiiteshave trace element abundances and Nd (     

The (Post)colonial Landscape of Cathedral Square: Urban Redevelopment and Representation in the “Cathedral City”1
