Mineralogical And Gemological Characteristics Of Metaophiolite Hosted Corundum (Malatya-Türkiye)

The corundum is found in the rocks of Berit metaophiolite Eastern Anatolia, near Doğanşehir a province Malatya. Metaophiolitic consist mainly garnet metagabbro, granulite, amphibolite, mylonitic amphibole schist, pyroxenite, orthopyroxenite, harzburgite, serpentinized dunite and diorite units. Corundum occurrences are mostly pyroxenites, amphibolites, peridotites granulites. Their colors change range between reddish pink, pink light pink. They usually structure translucent, vitreous sometimes cracked. seen scattered or clustered together inside which they found. size their crystals ranges from 0.5 cm to 10 euhedral observed pseudohexagonal form. As result petrographic examinations, it was that pyroxene, amphibole, plagioclase minerals accompanied with corundum. samples containing has qualifications will be as an object gemstone ornament by means cutting shining. Large specimens can processed alone. Samples, being small granules rock host rock. In samples, obtained patterns like zoisite were great demand world market.
