Summary

Rare minerals testify to unusual conditions of formation and they indirectly provide information about important geological processes, such as ore deposition. Some new minerals may have unusual properties (e.g., magnetic), making them of interest for materials science in general.

With the aim to document occurrences, modes of formation and to determine crystal structures, optical and physical properties of rare and new mineral species we apply a variety of techniques including X-ray diffraction and spectroscopy techniques, Infrared, Mössbauer, and Optical Absorption. spectroscopies at high spatial resolution.
