ABOUT STAURILITE AND ASSOCIATED MINERALS IN THE RARE METAL GRANITE PEGMATITES
For the first time, staurilite has been found in rare-metal granite pegmatites. This mineral was formed there as a meta-stable phase oversaturated with silica, and became the common staurolite with emulsion dissemination of quartz. Staurolite is there the selective concentrator of d-elements of the Fe group (from vanadium to zinc) and light lanthanides (La-Eu).
