Mit der brillantesten Röntgenquelle der Welt haben Forscher erstmals einen Blick ins Innere von geschmolzenem Magma unter den Bedingungen des tiefen Erdmantels geworfen. Die Untersuchung an DESYs Forschungslichtquelle PETRA III enthüllt, dass geschmolzener Basalt unter hohem Druck, wie er im Erdmantel herrscht, seine Struktur verändert. Bei Drücken von bis zu 60 Gigapascal, das entspricht einer Tiefe von 1400 Kilometern unter der Erde, geht das Magma in einen steiferen und dichteren Zustand über, wie die Wissenschaftler um Hauptautorin Chrystèle Sanloup von der Universität Edinburgh im britischen Fachjournal "Nature" berichten.
