Laboratory of Rock Magnetism

The laboratory is equipped with all the necessary equipment for the collection, processing and measurement of magnetic anisotropy of rocks. Samples are measured on a KLY5 kappabridge with modules for measuring the temperature dependence of magnetic susceptibility and a 3D sample rotator. The lab has a new JR-6A magnetometer with LDA5 demagnetization and PAM1 magnetization units , which is the most sensitive and accurate instrument for measuring remanent magnetization of rocks and soils. These methods are used to analyse and quantify the structure, deformation and flow of geological bodies, including fine-grained rocks.

  • Further information about the laboratory can be found here and here.
  • Those interested in thesis topics in rock magnetism or in measuring their own samples are welcome. Contact me at the email or phone number listed above

Research interests

  • Field geological mapping, structural geology, tectonics, and volcanology
  • Microstructural analysis of textures, structures, and deformation fabrics of igneous rocks
  • Fabric analysis of magmatic rocks and their record in geodynamic processes
  • Rock magnetism, paleomagnetism, and application of the magnetic anisotropy on volcanic, plutonic, and sedimentary rocks

Professional expertise

  • Crustal magma emplacement processes, volcano-plutonic link, collapse calderas, and interplay of magmatism with far-field tectonic deformation
  • Working on magmatic complexes in the Bohemian Massif (Austria, Czech Republic, Germany, Poland), Pyrenees (Catalonia), Western Carpathians (Slovakia), Rio Grande Rift (New Mexico), San Juan volcanic province (Colorado), Sierra Nevada (California), Blue Mountains province (Oregon), and Superior Province (Canada)
