Abstract:

Beryl-columbite pegmatite from Branná, Hrubý Jesenik Mnts., Northern Moravia

Granitic pegmatite from Branná represents typical beryl-columbite pegmatite of the Hrubý Jeseník Mts. pegmatite field. Its internal structure, textural-paragenetic units and description of minerals are given.

Columbite-tantalite is a typical accessory mineral besides garnet and beryl. Dominant ferrocolumbite is enriched in Ti and Fe3+ relative to columbite-tantalite from other localities of this region.
