Petrology

Lupe [1]

Petrological research interests are generally two-fold, including (1) experimental petrology and (2) field-related petrological studies.

In the last years, experimental studies were carried out on amphibole, tourmaline and on epidote minerals, with the special emphasis of element partitioning between fluid and solid. New fields of research include the determination of possible apatite-britholite and berlinite-coesite solid-solution series as well as the berlinite-variscite phase transition. Field-related petrological studies were and are currently being carried out in the Andes, NW Argentina, with a special focus on the evolution of the continental crust and the upper mantle, in the Tauern Window, Alps (Italy/Austria), the Münchberg area (Germany), the Cyclades Crystalline Complex (Samos, Greece), and the Rogaland Sector (SW Norway), with emphasis on P-T-t paths of high-grade metamorphic rocks. A special theme is the investigation of the petrogenesis of igneous anorthosite, syenite and ferrocarbonatite suites of NW Namibia and genetically related metasomatic sodalite deposits.

Microtectonics

Lupe [2]

Research in microtectonics is mainly concerned with the structural and metamorphic evolution of high-grade crustal rocks. Special attention is drawn to those segments of the crust, which have been deformed at P-T conditions that facilitated partial melting. The rheology of partially molten rocks probably controls as a first order factor the mechanics of over-thickened crust in (post-)collisional settings (e.g., Variscides, Himalayas), in subduction orogens (Andes), and in mobile belts (e.g. Sierras Pampeanas in W Argentina), with the rheological behaviour of these rocks changing dramatically when anatectic melt appears or vanishes during a kinematic process.

Applied Mineralogy

In the applied mineralogy we have experience in analyzing natural, synthetic, archaeological and industrial samples with various spectroscopic methods using X-ray and synchrotron radiation (DTA-TG, Infrared, Raman, UV-Vis, EXAFS, X-ray diffraction, SEM/EBSD, pole figure goniometer, high pressure experiments with the diamond anvil cell and geochemical analyses with standard methods). The goal of the studies is to characterize the structural and physical properties of the samples focussing on the near/long-range order and the texture of the sample under different formation conditions (temperature, pressure, …) using also in situ experiments.

Special Mineralogy

The Mineralogical Collections are representing science history of mineralogy since 1781 and the foundation of the "Königliche Bergakademie Berlin" in 1770. The following services are offered: guidance, lectures, lending of pieces for exhibition purposes, samples for scientific research purposes etc. Related research is concerned with twins, epitaxies, pseudomorphs and special mineral parageneses from localities world-wide.

Archaeometry

The Tell Halaf-project [3]: Tell Halaf is the modern name of the Aramaic city of Guzana in NE Syria, near the border to Turkey. It was built c. 1000 B.C. after the decline of the Hittite empire. Max von Oppenheim (1860-1946) explored the site in the years 1911-1913 and 1929. Parts of the monuments of the so-called Western Palace, famous for its entrance façade with columns shaped as monumental deities standing on their sacred animals were brought to Berlin in 1928, where they were presented in a provisional Tell Halaf Museum. During World War II the museum was completely destroyed by bombing during an air raid in 1943, but fragments of the statues and artefacts were recovered and stored in the Pergamon Museum. It is planned to incorporate the restored entrance of the Western Palace of Tell Halaf in the Pergamon Museum as the new entry to the Museum of the Ancient Near East in 2019. The Tell Halaf-Project started with the sorting and restoration of the art works. However, many fragments are still without correct assignment, which is one of the major archaeometric tasks. The statues were made from rocks of basaltic flows, with considerable heterogeneity, comprising massive as well as amygdaloidal types. Another archaeometric question is the exact location of the original quarries, where the raw material was extracted.
