Improving knowledge of crystal chemistry and systematics of minerals
Research aims to improve knowledge of the crystal chemistry of uncommon minerals or to provide new structural and chemical-physical data on minerals that are not yet characterized or only marginally known. By reviewing known crystal structures of minerals or determining the crystal structures of new phases, we also contribute to improving knowledge of systematic mineralogy. Interest is focused on both natural and synthetic crystalline compounds that have, or could have, potential technological interest.
