Infrastructure belongs to:

This laboratory deals with magnetostratigraphic dating of paleoclimate archives and the reconstruction of geomagnetic field variation in the geological past, as well as with analyses of magnetic minerals.

Therefore, intensity and directions of sedimentary magnetizations are determined. Further, magnetic minerals are characterized by their physical properties, such as coercivity, Curie temperature, grain size, and concentration, as well as by their chemical composition and preservation status.

  • Spectrophotometer

    Spectrophotometers are photometers that measure the intensity of radiation as a function of frequency (or wavelength) of the radiation; radiation enters the meter through a slit and is dispersed by means of a prism.

  • Variable Field Translation Balance

    The variable field translation balance (VFTB) is an instrument for measuring isothermal magnetizations in variable fields (e.g., hysteresis loops) as well as the temperature dependence of the associated magnetic parameters. It is specifically designed to measure the weak magnetizations commonly encountered in rock magnetism. (Source: https://doi.org/10.1007/978-1-4020-4423-6_312)
