The laboratory for thin-section preparation is specialized in the preparation of thin sections of soft and unconsolidated lacustrine and marine sediments, soils, hygroscopic sediment samples such as salts and clays, and freeze cores, as well as of hard rock, minerals, ores, and grain samples.

Thick and thin sections, ultrathin sections, polished sections (single and double-sided), grain mounts (minerals embedded in epoxy), single crystal slides and reference samples of various formats can …

The sample preparation laboratories provide facilities to prepare geological samples for a wide range of analytical methods. These include mineral separations for geochronologic analysis, mineral powders for geochemical analysis and polished thin sections for microscopy.

A special grinding laboratory enables the production of thin sections of various rock types. Precision saws in various sizes, a grinding machine (MPS), a lapping machine (Logitec) and a polishing machine are available for this.
