| Abstract: | 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 ( |
