The Geoinstitut is provided with well equipped machine shops, an electronic workshop and sample preparation laboratories. It has also access to the university computer centre.

The Geoinstitut welcomes applications for visiting scientist positions. The duration of such positions can range from two weeks up to two years or more. Longer-term appointments are usually for 2.5 years with the possibility of extension up to a maximum of five years total. Decisions concerning long-term appointments are normally made three times per year, in January, May and September. Applications may be submitted at any time to the Director, at the address given below, and should consist of a curriculum vitae, list of publications, a short statement of research interests and details of three referees.

Other fellowships including AvH, DAAD, DFG, EU can be utilized at the Geoinstitut. The institute may give assistance in applications for such funding.
