Abstract

The dissertation at hand comprises three independent chapters The first chapter contains for the first time a comprehensive data set from the enigmatic Marie Byrd Seamount province including morphological, geochronological, and geochemical data, combined with additional data for the De Gerlache and Peter I Island volcanic complexes. The centerpiece of this study is the 40Ar/39Ar dating of 9 samples including the Marie Byrd Seamounts and the submarine base of Peter I Island. The second chapter is focused on a geochronological and geochemical study presenting new 40Ar/39Ar age and XRF, ICPMS element concentration data, from recovered plutonic and dyke rocks of the Pine Island Bay region, Marie Byrd Land. The third chapter encompasses a major and trace element study on diffuse intraplate volcanism of the Christmas Island Seamount Province (CHRISP), situated in the northeastern Indian Ocean.
