Our group runs two laboratories: Laboratory of Rock Magnetism and Laboratory of Experimental Tectonics.

Laboratory of Rock Magnetism (head Filip Tomek) is equipped with high-end facilities for field sampling, measuring the magnetic susceptibility of oriented specimens, and statistical data processing and interpretation. We use a tuned-up hand-held drill Tanaka TED-262 for taking oriented samples in the field, the Laboratory is fully equipped with the newest models of multi-function Kappabridge MFK-1A with 3D rotator, CS4 Furnace Apparatus, and CS-L Low-temperature Cryostat Apparatus. The data are processed using the Anisoft software.

The Laboratory was founded in 2010 thanks to the financial support from the Department of Earth Sciences, Faculty of Science, Charles University in Prague (in part through the Ministry of Education, Youth and Sports of the Czech Republic Research Plan No. MSM0021620855), and also benefits greatly from a close collaboration with AGICO, Inc (Advanced Geoscience Instruments Company). AGICO ( is a private company based in Brno, Czech Republic, producing top-class geophysical instruments for measuring magnetic properties of rocks.


Kappabridge MFK-1A

The multi-function spinner Kappabridge MFK-1A is the world’s most sensitive commercially available instrument for measuring the bulk magnetic susceptibility (material property that reflects magnetization of a substance with respect to the applied magnetic field) and its anisotropy in rocks and other materials. Taking measurements using the Kappabridge is very rapid (one specimen per 2–3 minutes) and extremely precise (the sensivity of the instrument is 10–8).
In Earth Sciences, the anisotropy of magnetic susceptibility (AMS) method has been used extensively to analyze and quantify rock fabric and to estimate finite strain and flow patterns in deformed rocks. One of the greatest advantages of the AMS method is that it enables fabric studies even in very fine-grained rocks with no macroscopic preferred orientation of mineral grains.

Our main goal is to develop geologic applications of the anisotropy of magnetic susceptibility (AMS) method and to promote research in rock magnetism at the Faculty of Science, Charles University in Prague. The Laboratory has been designed exclusively for non-commercial scientific purposes, primarily for students and faculty members. Using the Laboratory is free of charge on the understanding that the users strictly follow the operating instructions.

Laboratory of Experimental Tectonics is equipped with highly sophisticated apparatus purpose-made by the Development Center of the Institute of Organic Chemistry and Biochemistry, Czech Academy of Sciences, able to simulate a wide range of geologic processes, mostly related to active continental margins and subduction of oceanic plates.
