Granite or Pegmatite? Picked from a field site, this coarse-grained rock shows pink feldspar crystals with shiny flakes of mica, classic features of a granitic material. The pink hue is from potassium feldspar (microcline/orthoclase), while the sparkle comes from muscovite and biotite. Such rocks form from slow cooling of magma deep in the crust, often marking continental crustal zones that may host rare metals or gem minerals in pegmatitic varieties. Possible rock type: Muscovite Granite or Peg

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
