Mineral assemblages of significant pegmatite dikes from the Hatě area near Dolní Bory Western Moravia

Significant pegmatite dikes from Dolní Bory – Dikes No. 1, 3, 4, 5, 6, 7, 8 and Oldřich were selected and localized within the Hatě area. Their mineral assemblages were specified in detail with respect to minor and accessory minerals and the minerals typical for the individual dikes. The pegmatite from the Hatě area near Dolní Bory are typical Al-rich with volumentarically abundant andalusite, schorl, sekaninaite, muscovite and several accessory minerals such as corundum, diaspore, pyrophyllite, dumorrierite, chloritoid and augelite. Iren is also a typical element in the studied pegmatites, it is dominant in almost all Fe, Mg, Mn minerals: sekaninaite, schorl, almandine, zwieselite, triphylite, ilmenite, wolframite.
