Most commonly, rock and mineral samples are prepared as thin sections or grain mounts for study in the laboratory with a petrographic microscope. Optical mineralogy is used to identify the mineralogical composition of geological materials in order to ...
New minerals approved by the International Mineralogical Association (IMA-CNMNC) are allocated unique symbols consistent with the main listing.
