A unique mineral specimen featuring staurolite, a twinned staurolite crystal, showcasing a distinctive cross-like shape and a reddish-brown color.
Geological Information:
- Location: Georgia, USA (notably in the Blue Ridge Mountains) - Type: Staurolite (Iron Aluminum Silicate, Fe₂Al₉Si₄O₂₂(OH)₂) - Formation: Metamorphic rocks, specifically in high-grade schists and gneisses - Color: Reddish-brown to dark brown - Hardness: 7-7.5 on the Mohs scale - Crystal System: Monoclinic - Formation Process: High-pressure and high-temperature metamorphism resulted in the formation of staurolite, often twinned in a characteristic cross-like shape. - Age: Paleozoic Era, approximately 480-250 million years old - Occurrence: Found in limited quantities, primarily in the Blue Ridge Mountains of northern Georgia, particularly in the Chattahoochee National Forest.
This detailed description highlights the natural beauty, unique features, and geological significance of Staurolite from Georgia, showcasing its rarity and mineralogical importance.
