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
