Research Interests

 

- textures and microstructures

- deformation processes and kinematics in crustal fault zones

- textures and (static) recrystallisation processes

- investigation of brittle-ductile marble shear zones in the seismic-aseismic transition zone

- investigation of deformational processes within dome structures and metamorphic core complexes

- development of graphite spherules in statically recrystallised marbles

 

Activities:

Co-Organisation of the Workshop "Actual Methods and Perspectivs in (Micro)fabric Analysis at the conference Tektonik, Struktur und Kristalingeologie (TSK 12) in Karlsruhe on 01.04.2008. Subject: New Perspectives in the Measurement of Global Textures (X-Ray and Neutron Diffraction)

Organisation of the Workshop on Future Applications of Neutron Texture and Powder Diffraction in the Geosciences from 15.11.2007 to 16.11.2007 at FRM-II in Garching near Munich, Germany

For details of our work and lab facilities at the University of Göttingen, please refer to our groups website.

The webpages and activities of our neutron diffraction group of the University of Bonn located at the research centre Jülich. Due to the shutdown of the research reactor FRJ-2 our diffraction group unfortunately had to be closed down.

Symposium Tektonik-Strukturgeologie-Kristallingeologie (TSK) 11 in Göttingen (Germany): Workshop Rocktextures (crystallographic preferred orientations) - Subjects: new strategies for measurements and data analysis, crystallisation/recrystallisation and deformation textures: processes, deformation mechanisms, kinematics and correlation of experimental, numerical and natural textures
