The Laboratory for Earth Magnetism in Time and Space deals with magnetostratigraphic dating of paleoclimate archive sand the reconstruction of geomagnetic field variation in the geological past. 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.

The Minolta CM 2500d is a portable e spectrophotometer, which is applied to determine the colour composition, the colour spectrum and colorimetric data of solid samples. The device works within 360 nm to 740 nm with a resolution of 10 nm.
