Mineralogy

Minerals and mineral deposits

Research and education within the fields of minerals, their occurrence, distribution and formation, with emphasis on deposits of rare and critical metals, including the rare earth elements. Field as well as laboratory based studies on Swedish and international deposits and mineralisations. Major techniques applied include in-situ microchemical analysis, X-ray diffraction, optical microscopy, various ICP and spectroscopic methods, as well as mass spectrometry for stable isotope analysis.

High temperature - high pressure mineralogy

The research is experimentally oriented and seeks to obtain information on properties of Earth’s materials under extremes pressure and temperatures. Using diamond anvil technique and laser heating, in situ HP-HT experiments are conducted; simulating conditions of the Earth’s deep interior. Applying conventional and synchrotron X-rays, and a range of optical spectroscopic techniques, physicochemical properties such as phase transitions, magnetism, thermal and electric conductivities are determined and used in geophysical and geochemical models. Research interests extend from the properties of iron in the Earth's core, through the mineralogy of mantle oxides and silicates, to crustal mineral-fluid interactions.

Functionally enhanced minerals for a green society

A natural connection extends from geologically-motivated studies on Earth’s materials towards material science, e.g. the search for novel multiferroic and thermoelectric materials, and environmentally-friendly processing and refining of natural resources into industrially valuable materials such as silica-based oxides and phosphate-glass ceramics. Synergy effects arise from the synthesis of fields of systematic mineralogy and materials science, undertaken on an international collaborative platform.
