Whitish rock alone does NOT mean lithium. Only when a whitish pegmatite shows coarse crystals, possible spodumene or lepidolite, and occurs within the right geological setting does it indicate lithium potential. Visual observation only tells us what is worth testing, not confirmation. #LithiumExploration #Pegmatite #Spodumene #FieldGeology #MineralExploration | NC Gideon

RECOGNIZING AN EVOLVED MICA PEGMATITE FOR LITHIUM PROSPECTS When a pegmatite starts showing elevated Rb, Cs, Ta, Sn, and Nb, it’s a strong signal that the rock is highly evolved , and could host lithium minerals. You’ll notice the mica color changes as the pegmatite evolves: Early stage: Dark brown to black (Biotite) Intermediate stage: Silvery or grey (Muscovite) Highly evolved: pink to purple (Lepidolite – lithium-bearing mica) So, if your mica pegmatite begins to shine with purple or lilac to
