The results show that the beryl occurs within a texturally and mineralogically variable matrix of phlogopite, muscovite, actinolite, plagioclase and pyrite, with occasional quartz, calcite and accessory minerals such as fluorapatite, titanite, rutile, chalcopyrite, molybdenite and rare tellurides. The beryl can occur as large, slightly altered grains in coarse-textured, hydrothermally altered, silicified zones, as well as at altered protolith contacts, as inclusions in other minerals (such as amphibole), and as a fine-grained, pervasive overprint that may represent a sodic alteration event.
