Deciphering the Tectonics of the Caucasus from Post-Collisional Volcanism
… centre of the Alpine-Himalayan orogenic belt, and differs from their better studied neighbours by the presence of intense, largely mantle derived post-collisional magmatism. Volcanism began 5-15 Ma after the initial collision occurred, and after the crust had already thickened to 45-60 km. This …

Characterization and chronology of refractory inclusions (CAIs) in the CV3 chondrite NWA 4502
In this thesis I report the petrographic, elemental and isotopic (oxygen, Al-Mg, Rb-Sr and uranium) compositions as well as U-Pb ages of five coarse-grained igneous inclusions (Type A CAIs 1 and 4a, Type B CAIs 5, 6 and 7) from the CV chondrite North West Africa (NWA) 4502 the second largest CV …

Geochemical and fluid dynamic investigations into the nature of chemical heterogeneity in the Earth's mantle
Variations in the abundances of elements and radiogenic isotopes in mantle derived peridotites and volcanic rocks are chemical integrals over time, space, and process, which ultimately contain information about the role of convection in the earth's mantle in creating, maintaining, and destroying …
