Dissertationsthema

Dipl.-Geol. Sarah Freund schreibt ihre Doktorarbeit in der Arbeitsgruppe Endogene Geodynamik bei Prof. Dr. Karsten Haase. Das Thema lautet „ The generation of felsic magmas in the ocean crust: assimilation-fractional crystallization processes versus re-melting of the crust“


Project summary

The PhD projekt is a geochemical study of the formation of felsic magmas within the ocean crust which will help to understand 1) fractionation processes leading to felsic crustal material, 2) the dynamicy of magma ascent in the ocean crust, and 3) the interaction of magmas with the hydrothermally altered wall rocks. The sampling locations are the felsic magmatic rocks of the Oman Ophiolite, the Troodos Ophiolite in Cyprus and a suite of basaltic, andesitic and dacitic lavas from the Pacific-Antarctic Rise.  

A experimental approach, using the same representative samples, will be carried out by a PhD student in the Institut für Mineralogie der Leibnitz Universität Hannover.
