Die Auswirkungen des CO2-Gehaltes der Archaischen Atmosphäre auf die Bildung von Siderit in Superior type Banded Iron Formations
Gäb, Fabian Matthias (2019-12-06)Es wurde vorgeschlagen, Siderit (<em>FeCO<sub>3</sub></em>) Archaischen Superior Type Banded Iron Formations zu verwenden, um eine Bestimmung des <i>CO<sub>2</sub></i>-Partialdrucks in der Archaischen Atmosphäre durchzuführen. ... -
Crystal chemistry, melt composition and redox controls on the behavior of trace elements during lunar magmatism
Leitzke, Felipe Padilha (2018-12-12)The behavior of trace elements in magmatic systems is controlled by physicochemical conditions prevalent during mantle partial melting and magmatic differentiation. Among these controlling factors are temperature, depth, ... -
Effect of iron and sulfur on the solubility of highly siderophile elements in silicate melts
Laurenz, Vera (2012-07-13)An important aspect in highly siderophile element (HSE - Os, Ir, Ru, Rh, Pt, Pd, Re, Au) geochemistry is their solubility in silicate melts. Knowing the solubility of HSE in silicate melts can potentially give insights on ... -
Fluid driven processes in the crust – the formation of anorthositic dykes in the Troodos ophiolite (Cyprus)
Zirner, Aurelia Lucretia Katharina (2017-10-12)Anorthositic dykes related with the Upper Cretaceous Troodos ophiolite are described for the first time. An entire anorthosite dyke swarm appears within the Limassol Forest Complex, crosscutting the supply channels of late ... -
Petrogenesis of Basalt-hosted sapphires from the Siebengebirge Volcanic Field (SVF) in western Germany
Baldwin, Lisa Christina (2016-04-29)Megacysts of blue sapphires are hosted by alkaline mafic rocks from the Cenozoic Siebengebirge Volcanic Field (SVF) in western Germany. Similar occurrences of sapphires related to intra-continental alkaline mafic volcanism ...
