Product Overview
Peridotite is an iron-rich ultramafic rock, with a chemistry that suggests genesis from a point deep within the crust, possibly as deep as the mantle. The large crystals indicate slow cooling within a magma chamber. Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises. This fascinating sample is useful for comparisons with other igneous rocks, and as part of lessons in Bowen's reaction series.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Pack of 12. Each set is individually packaged, labeled & barcoded for easy identification and storage.
