Raw Peridotite Igneous Rock Hand Sample, Approx 3 inch Category_Plasticware and aquatic vertebrate morphology forPERIDOTITE 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 GREAT FOR GEOLOGY CLASSROOMS Ideal 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 GEOLOGIST SELECTED
