Project descriptions:

1) High-pressure Palaeoproterozoic rocks of the Santa Maria Chico Complex were investigated using modern geothermobarometric methods to better understand the development of orogenic lower crust during the relatively early history of the Earth.

2) A new hypothesis for the genesis of the famous amethyst occurrences in Parana basalts is tested. For that purpose, the alteration of the basalts and rheological parameters of altered basalts are studied. In addition, stable isotope studies are undertaken on various materials of the amethyst geodes.

3) The concentration of platinium group elements in Parana basalts is studied to explore the economic potential of these widespread flood basalts.

4) High-pressure granulites of southern Minas Gerais with potential ultrahigh pressure rocks are investigated to better understand collisional processes during the Panafrican orogeny.

Project description:

The German-Chilean group is studying various accretionary wedge complexes along the Chilean Coastal Cordillera (from latitude 30°S to Tierra del Fuego) which have formed during the collision of the South American plate with oceanic plates from Carboniferous times on. Mainly P-T paths are derived for various lithologies (metapelites, metabasites) to understand the mass flow in such accretionary wedge complexes. Numerical modelling is achieved to support field and laboratory work.

In addition, the timing of the corresponding geodynamic processes leading to the formation of high-pressure rocks is investigated. A conclusive scenario for the collision of the Indo-Australian and the Asian plates from Cretaceous times on should emerge from these studies.

Project description:

Metamorphic rocks from the Rif Mountains, northern Morocco, are characterized using petrological methods. In particular, high-T granulite facies rocks are considered that have been buried to mantle depths. The results are interpreted as due to a counterclockwise P-T-path reaching T as high as 1000°C. In addition, low-T, high-P metamorphic sediments containing relics of the indicator mineral magnesiocarpholite are studied.
