The Dendrochronology Laboratory aims to reconstruct the temporal and spatial variability of the climate of the past utilizing multi-parameter tree ring analysis and to assess and verify the causes of climate change and its impact on woody plants. The lab is equipped with various technical field equipment, sample preparation tools, a LINTAB tree-ring measurement system and a calibrated optical scanner incl. analsysis software for dendrochronology, instruments to determine the wood chemistry …

The thin section preparation is used to make or produce sections of soft sediments (lacustrine and marine), hard rock, minerals, frozen kernels, organic materials, soils, ores and hygroscopic samples such as salts and clays. Thick and thin sections, ultrathin sections, polished sections, polished sections (single and double-sided), scattering devices, single crystals and reference samples of various formats can be produced. These are then used for further analysis on optical microscopes as …

Mineralogical preparation covers the spectrum of coarse and fine sawing work, polished sections and thin sections polished on one or both sides. Surface and thin sections can be produced in Giessen format or as one-inch cylindrical sections. The laboratory is equipped with various rock saws, an inner diameter saw, two GNM grinding machines, two Logitech polishing machines, and a polishing machine for vibration polishing.

The preparation lab offers different preparation methods such as thin-section production, polishes, dye methods, hardening methods and others.

In the Rock-Lab thin-section, thick-section, polished-section and separation work can be used for teaching and research. The thin-section preparation is an important method for working on paleontological, geological and mineralogical questions.

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 …
