SemesterFrühjahrssemester 2016
Periodizitätjährlich wiederkehrende Veranstaltung
LehrveranstaltungFindet dieses Semester nicht statt.

KurzbeschreibungAnisotropy of rocks: from laboratory measurements to numerical prediction. Link between structural geology, petrology and geophysics.
Rheology of rocks: from laboratory measurements to flow laws used for numerical modelling. Special emphasis on plastic deformation.
LernzielGive laboratory experience for the determination of physical properties of rocks and comparison with the numerical prediction.
InhaltDescription of physical properties (seismic, thermal and electrical conductivity, permeability etc.)
Elasticity in isotropic media.
Microscopic aspects of anisotropy.
Elasticity and seismic velocities in crystals.
Elasticity in polyphase rocks.
Exercises with software (Mainprice) to calculate seismic properties.
Methods for the measurements of seismic properties of rocks in Laboratory. Practice on the bench with the oscilloscope.
Anisotropy at different scales.

Rheology and deformation mechanism: from single phase to polyphase rocks (solid state).
Measurements and elaboration of LPO, SPO using OIM, Beartex, Surfor and Paror software.
Introduction to rheology and flow laws.
Deformation mechanism maps, crustal strength profiles and extrapolation from experiment to nature .
Experimental rock deformation techniques (stress-strain curves etc.).
Experimental deformation in Laboratory. Practice using uniaxial experimental set-up. Example in the brittle field.
Experimental deformation practical in the Paterson gas rig.
