— Staurolite has been found in rare-metal granite pegmatites for the first time. The mineral is formed as a metastable phase oversaturated with silica and transformed into the common staurolite with emulsion disseminations of quartz. Staurolite selectively concentrates d elements of the Fe group (from V to Zn) and LREE (La-Eu).

Sillimanite nodule in a biotite gneiss. The sillimanite grew by the reaction muscovite + quartz = sillimanite + K-feldspar + H 2 O. Small amounts of muscovite in the foliation are still present, so the reaction did not run to completion. Microcline and quartz can also be distinguished in the image, so this represents the reaction assemblage.
