Pegmatite rocks are a great source of construction aggregates, road aggregates, and as a base material in landscaping & outdoor paving in nearby areas of pegmatite quarries or mines. Architectural Uses of Pegmatites in Dimension Industry: Due to stunning appearance and mineral values, pegmatites are high-quality decorative aggregates.

2.3 Pegmatite. Pegmatites are igneous rocks with very large crystals – usually, most of the crystals will be greater than 1 cm in length. In igneous rocks, the presence of large minerals tells us that the rocks cooled very slowly from their molten state to what we see today.

Rare-element pegmatites are divided into two end member composition groups (Cerný, 1991):Lithium–Caesium–Tantalum (LCT) pegmatites are enriched in Li, Cs, Ta, Be, B, F, P, Mn, Ga, Rb, Nb, Sn, and Hf. Major LCT pegmatite deposit examples include the Tin Mountain pegmatite in the United States, Tanco pegmatite in Canada, Altai Number 3 pegmatite in China, the Greenbushes, …

Miarolitic pegmatites emplaced at shallow levels under low pressure retain a vapor phase in the melt upon ascent through the Earth's crust. Much to the satisfaction of the lucky gem or specimen miner, these ultimately form miarolitic cavities - large crystal-lined pockets, in which spectacular crystals of beryl, tourmaline, spodumene, topaz, and accessory minerals can occur.
