Raw Phyllite Metamorphic Rock Hand Sample, Approx 3 inch

This 3-inch hand sample of phyllite represents a classic example of low-grade metamorphic transformation. Derived from shale or slate, phyllite retains a fissile structure but exhibits a distinctive satin-like sheen and fine foliation from the alignment of platy minerals during metamorphism. Its texture is easily distinguishable from its parent rock, offering students a clear visual and tactile comparison. Each specimen is individually labeled and barcoded, and comes packaged in a clear storage bag. Ideal for NGSS-aligned geology lessons on rock transformation, structure, and classification. Sourced globally and hand-processed in Victor, NY.
