Jaw crushers are available for crushing rocks and other geological samples. Various mills (vibrating disc mill, McCrone mill) are available for further processing, which pulverize the granulates for further analysis.

The section is well equipped for rock crushing, sieving and milling, preparation of thin and polished sections and grain mounts, and mineral separation by gravimetric and magnetic methods. We maintain central facilities and equipment for cleaning, crushing, sieving and grinding rock samples, both for preparation of homogenized whole rock powders and for the production of mineral separates. Whole rock powders (grain sizes < 62 μm) are typically used for X-Ray diffraction (XRD), X-Ray …

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.

Samples that are to be examined with the aid of a microscope must be prepared specifically for the instrument. To do this, the conditions of the instrument and the sample holder must be known: sample size - sample height or thickness - surface condition - conductivity - vacuum resistance. For any examination procedure, the sample should first be viewed with a light microscope.
There are preparation facilities for the use of the available equipment. This option is primarily intended for users …
