Laboratory for Physical Geography

Sedimentology, Soil science, Geochemistry, Environmental analysis

 

Within the laboratory for Physical Geography at the University of Cologne a many-faceted spectrum of geoscience methods is available for the scientific projects, theses and laboratory practical courses. Since 2004 on a total of 800 m2 the laboratory offers a broad spectrum of methods for manifold geoscience questions. The main focus of the laboratory is the sedimentology, geochemistry, soil science and archaeology. Laboratory work is mainly a subject of dissertations, external funds and theses in connection with scientific projects. In context of interdisciplinary practise, the laboratory offers the opportunity for external commissioned work (e.g. collaborative research centre).

Besides scientific work the laboratory is used also for laboratory courses for master and bachelor students.

The requirement for the work for students in the laboratory is the completion of a laboratory course and the instruction according to the laboratory regulations.
