1. 11. Numerical and laboratory studies of seismic properties and elements of rock fabric from the microscale to the macroscale

   Författare :Mohsen Bazargan; Bjarne Almqvist; Qin Wang; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Physical properties of rocks studied in the laboratory are useful to provide constraints on the dynamics of Earth?s interior. This may include direct constraints on in-situ seismic properties, such as elastic wave velocity measurements that can be compared to seismological data, or petrofabric indicators such as anisotropy of magnetic susceptibility (AMS).

3. 12. Geophysical tools for prognosis of deformation in hardrock environments

   Författare :Mai-Britt Mose Jensen; Satu Mertanen; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AMS; Bergmekanik; Refleksions seismik; Gravimetri; Petrofysik; Tillämpad geofysik; Applied Geophysics;

   Sammanfattning : Underground mining of the Kiirunavaara iron mineralization is causing large-scale deformation of the hangingwall of the orebody. To understand and possibly predict future deformation, a structural model of the hanging wall and a good understanding of the petrophysical and mechanical properties of the constituent rocks is necessary.

4. 13. The Kirunavaara hangingwall : a geophysical and petrophysical analysis

   Författare :Mai-Britt Mose Jensen; Håkan Mattsson; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

   Sammanfattning : Underground mining of the Kirunavaara iron mineralization is causing large-scale deformation of the hangingwall of the orebody. To understand and possibly even predict this deformation, a good understanding of the elastic and mechanical properties of the rocks in the hangingwall is necessary. LÄS MER
