GNEISS ROCK
Mineralogical Segregation: Features distinct, coarse-grained gneissic banding (foliation) characterized by the systematic separation of light-colored felsic minerals, such as quartz and feldspar, from dark-colored mafic minerals like biotite and amphibole.
High-Grade Crystalline Structure: Composed of recrystallized mineral grains formed under extreme high-pressure, high-temperature (HPHT) conditions, ensuring superior mechanical density and structural integrity suitable for precise petrographic thin-sectioning and geochemical assaying.

GNEISS ROCK This gneiss rock specimen shows distinct mineral banding formed under high-grade metamorphism, supporting lessons on metamorphic facies and structural geology.
GNEISS ROCK is priced at approximately ₹235 (indicative market benchmark, incl. GST, August 2026).
Product Description
This gneiss rock specimen shows distinct mineral banding formed under high-grade metamorphism. The visible banding makes gneiss a useful teaching example for identifying metamorphic facies and understanding how crustal deformation and heat reshape rock structure over geological time. It supports petrological study and structural geology coursework at the secondary and university levels.

Frequently Asked Questions
What causes the banding pattern in gneiss?
The banding forms under high-grade metamorphism, where heat and pressure separate minerals into visible light and dark bands.
What is the exact specimen size?
This has not been independently verified for this listing — confirm with STEMAids before ordering.
Is this suitable for secondary school coursework?
Yes — gneiss specimens of this kind are standard teaching material for metamorphic rock identification.
Does this carry a specific quality certification?
Any certification is manufacturer-stated — verify current certification and scope directly with STEMAids before relying on it.
Does STEMAids supply other metamorphic rock specimens?
