"During the Workshop "Non-destructive Evaluation of Physical Properties" we decided to call the colleques who are interested to organize and participate in a Workshop on 'Petrophysics and Geological Disposal of Radioactive Waste' for spreading of experience and harmonization of practices as well as summarizing of different approaches, connections and applications (for example Rock Mechanics, Pore Space Characterisation, Texture Analysis, Radionuclide Retardation, Thermo-Hydro-Mechanics etc.). If you have any colleaques who may be interested in this activity, then please direct them towards my e-mail: vlad@igem.ru or mmontoto@asturias.geol.uniovi.es.



Scope of the conference

Lattice preferred orientation (texture) is one of several important properties of rocks. The texture reveals information on the evolution of rock fabrics and on the mechanisms of fabric development. In addition, it can control the anisotropic physical rock properties to a large extent.

Due to the low symmetry of many minerals and the polyphase composition of rocks geologists have high requirements for the texture analysis. These requirements are met by recent extensions of the standard techniques for texture measurements, e.g. neutron diffraction to determine the global texture of large sample volumes and electron diffraction to measure single grain orientations. Even in the fields of quantitative texture analysis and numerical texture simulation materials scientists and mathematicians recently refined their methods, which are now more accessible and easier to apply for users like geologists, who are mainly interested in the application of all these methods.

The demonstration of new methods is one scope of the conference. Another goal is to demonstrate the application of texture analyses for a better understanding of the evolution of rock fabrics at all scales. In addition, special interest will be given to the close relation between texture and anisotropic physical rock properties, which became of increasing interest during the last few years.

The aim of the meeting is to improve the cooperation between materials scientists and geologists and to involve scientists from related fields of research, like glaciologists (ice textures/properties) and biologists (biomineralisation). We hope to encourage interdisciplinary discussions to develop new applications and joint projects for texture and physical property analyses.
