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

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

How to recognise Lithium-Bearing Pegmatite in the Field through Visible Mineral Zoning FRACTIONATION PROGRESSION In the field, pegmatites often reveal their evolution through visible mineral zoning , a reflection of magmatic differentiation as the melt cools and evolves. Early-stage pegmatites → dominated by biotite (dark brown to black). Intermediate-stage pegmatites → show abundant muscovite (silvery). Highly evolved pegmatites → characterized by lepidolite (lilac or purple), which is lithium-
