Pegmatite, an igneous rock, hosts precious gems like emeralds, tourmalines, and aquamarines. Their large grains are rich in minerals, formed in specific conditions where magma cools slowly, organizing crystals into gem-filled formations. #Pegmatite #IgneousRock #Emeralds #Tourmalines #Aquamarines #Gems | Mineral Gemstones | Facebook

Pegmatite Geochemistry: An Insight A sample from an active lithium mine (~3% Li₂O) was analyzed using a handheld XRF and gave the following results: Rb = 4400 ppm, Cs = 263 ppm, Ta = 0 ppm, Sn = 50 ppm, Nb = 6 ppm. Despite coming from a lithium-rich zone, the Ta, Sn, and Nb values are quite low compared to other LCT (Lithium-Cesium-Tantalum) pegmatites observed in Nassarawa State of Nigeria. This suggests that: 1. The Li enrichment may have occurred independently of Ta–Nb–Sn mineralization, poss
