Peridotite Specimen

This class pack contains 12 raw peridotite specimens, each approximately 1" in size, individually packaged in transparent bags and labeled with barcodes for easy identification and storage. Every specimen is selected and hand-processed by a geologist to ensure it exhibits the defining characteristics of peridotite. Peridotite is an iron-rich ultramafic igneous rock with a chemistry that points to formation deep within the Earth's crust, possibly as deep as the upper mantle. The large crystal structure visible in these specimens indicates slow cooling within a magma chamber. The coarse-grained texture and dark, olive-green coloration make peridotite a distinctive and instructive sample for geology coursework. These specimens are ideal for identification and classification exercises, comparisons with other igneous rock types, and lessons on Bowen's reaction series. The 12-specimen class pack format provides enough material for group study and hands-on examination across an entire classroom. All specimens are sourced from locations around the world and processed in Victor, NY.
