Research in isotope geology
My main research interests are planetary sciences and especially lunar geology. At the moment, I am part of a project which aims to obtain a better understanding of the impact history of the Moon in order to test the theory of the proposed Late Heavy Bombardment (LHB) around 3.8 - 4.0 Ga. It is assumed that the LHB was not restricted to the Moon but also occurred on Earth and other planetary bodies within the early Solar System. Therefore, the LHB theory also has significant implications in terms of the origin and the earliest evolution of life on Earth.
I am investigating lunar impact breccias sampled during the Apollo missions. I analyze their texture and chemical variations, identify microstructures in zircon and obtain precise U-Pb zircon and phosphate ages using the NordSIMS ion microprobe. The U-Pb ages will help to establish a precise chronology of distinctive breccia types collected at different Apollo landing sites.
