Short summary
In the paper we discuss the origin of large chamber pegmatite bodies which contain giant gem-quality crystals of black quartz (morion), beryl, and topaz. We conclude that these pegmatites develop under the influence of later intrusions of mafic rocks that cause reheating of the partly crystallized granite massifs and that they supply a large amount of fluids that facilitate the inflation of pegmatite chambers and crystallization of giant crystals of various minerals.
