Isotopic age data from early studies of ancient lunar breccia were often lacking sufficient petrological background information. In-situ U-Pb dating of accessory phases in lunar rocks not only provides precise ages but also preserves their petrological context. This information is crucial to reconstruct geologic events in the early lunar timeline, notably the history of basin-forming impacts. To overcome this issue we combine state of the art analytical techniques to further constrain the impact history of the moon:

  • Quantitative Evaluation of Minerals by Scanning Electron Microscopy: QEMSCAN® (IML RWTH Aachen)
  • Raman Spectroscopy (Freie Universität Berlin)
  • Electron Microprobe Analysis (Freie Universität Berlin)
  • Scanning Electron Microscopy (Freie Universität Berlin)
  • Secondary Ionization Mass Spectrometry (Geoforschungszentrum Potsdam)
