Microlite plate
Discover rare microlite mineral specimens and crystallised tantalum plates from high-altitude lithium pegmatites. Featuring sharp, lustrous octahedral microlite crystals nestled on crystalline feldspar, cleavelandite, and lepidolite matrix.
Rare Earth Tantalate: Microlite on Pegmatite Matrix
As a key member of the pyrochlore supergroup, microlite is an uncommon calcium-sodium tantalum oxide mineral found strictly in highly fractionated lithium-cesium-tantalum (LCT) pegmatites. Formed in late-stage hydrothermal cavities, crystallised matrix plates of microlite are prized by systematic and rare-species collectors.
Key Specimen Characteristics:
- Crystal Habit: Sharp octahedral and modified dodecahedral crystals displaying high specific gravity and adamantine-to-resinous luster.
- Coloration: Ranging from honey yellow and caramel amber to deep reddish-brown and olive tones.
- Matrix Contrast: Well-crystallised microlite perched securely against snow-white albite or lilac lepidolite plates.
Every piece is 100% natural, untreated, and verified for crystalline integrity.
