Geodiversity: Crystal structures and properties of new and rare mineral species
As in biology, new, previously unknown species continue to be discovered in the geosciences. For the scientific recognition of a new mineral species, crystal structural, chemical and physical data have to be determined according to the specifications of the International Mineralogical Association and checked and confirmed by it ...

Composition, temperature and pressure dependence of phonons in hydrous complex silicates
Currently, the mineral supergroups amphiboles (AB2C5T8O22W2) and tourmalines (XY3Z6T6O18(BO3)3V3W) which are relevant in wide areas of geosciences, are the focus of our crystal chemical investigations using Raman spectroscopy. For example, amphiboles are rock-forming minerals in many rocks and their species are representative of the different rock types and their chemical composition ... [ more ]
Understanding written artefacts
Written artefacts can tell us much more than meets the eye. Apart from their written content or design, the great variety of artefacts’ materials stores a wealth of information – about their production and preparatory treatment, practices of writing, use and reuse, storage and deterioration, as well as possible traces of conserving interventions ....
