Research

Late accretion onto the Moon and Earth

The moon is the only planetary body other than the Earth for which we have enough samples to reconstruct large- and small-scale processes like core-mantle differentiation, crust formation and subsequent formation of impact related structures and lithologies of variable size. In contrast to terrestrial samples, ancient lunar impact rocks retain a direct compositional and chronological record of late accretion which took place mainly from 4.4 to 3.8 billion years ago. Lunar impact melt rocks and impact breccias are produced by single or multiple impacts and are mixtures of impactors and different crustal rocks. Highly siderophile elements (HSE) like iridium, platinum and gold and siderophile volatile elements like copper, silver, tellurium, selenium and sulphur determined in such impact rocks provide insights into the composition of impactors as well as small-scale processes during impact rock formation. Furthermore, abundances of siderophile volatile elements in pristine lunar rocks (i.e., endogenous igneous rocks that have very little or no contamination with impactor material) help to constrain processes during formation of lunar reservoirs and are a prerequisite for interpretation of the lunar impactite data. By comparison with Earth and differentiated meteorite groups which are attributed to planets like Mars and asteroids like Vesta, we seek to understand the element inventory element budged of late accreted material onto terrestrial planets.

Anorthosites of the Kunene Intrusive Complex

Massif-type anorthosite complexes are characteristic features of the Proterozoic crust. Their apparent temporal restriction to the Proterozoic suggests unique tectono-thermal conditions during this period. The 18,000 km2 Kunene Intrusive Complex (Namibia/Angola) is one of the largest massif-type anorthosite complexes in the world. The rocks of the Kunene Intrusive Complex display well preserved magmatic cumulate textures and original mineral compositions, and hence allow the direct investigation of igneous processes active during their formation. In order to constrain the source of the parental melt and the impact of crustal contamination the anorthosites were investigated for their lithophile and highly siderophile trace element composition and their oxygen, strontium, neodymium, lead and osmium isotopic composition.

Tauern Window

The Tauern Window is the largest tectonic window in the Eastern Alps and exposes the Pennine nappe complex and underlying units of the European continental margin. The petrologic record of this area gives unique insights into processes during formation and subduction of the Tethys ocean floor, collision of European margin and the Adria plate, and the exhumation of the metamorphic nappe complex. Investigation of mineral assemblages and isotopic dating help us to determine P-T-t paths for different units within the Tauern Window and to resolve deformation and tectono-metamorphic history of the Eastern Alps. The formation age of the Alpine Tethys is well constrained in the Western and Central Alps but robust age constraints are lacking in the Eastern Alps. The intrusion age of mafic plutons can help to determine the time of oceanic crust formation and to constrain its affiliation to either the Liguria-Piemont or Valais oceanic basin of the Alpine Tethys. This distinction is crucial to paleogeographic reconstructions and our understanding of tectonic processes in the Alpine collision zone.
