Abstract

The Bonče tourmaline-bearing pegmatite is situated approximately 150 km southern from Skopje, Republic of Macedonia, on the western slopes of the Selečka Mts. The Selečka Mts. belongs to the Eastern Pelagonian tectono-stratigraphic unit of the Dinaride-Hellenides. It comprises Precambrian ortho- and paragneisses, micaschists and amphibolites and hosts numerous pegmatites which differ according to their size, the mineralogical features, the internal structures and the fractionation degree. The Bonče pegmatite belongs to the group of simple pegmatites with simple mineralogy and weakly developed zonation. The wall zone comprise black-colored, up to 10 cm elongated prismatic tourmaline. According to chemical composition and XRD data tourmaline is determined as dravite. The pegmatite core is characterized by predomination of massive quartz. Textural features and fluid inclusion data suggest that the Bonče pegmatite formed as a result of subsequent crystallization from a granitic melt.
