Get acquainted with one of the most interesting products of geological processes with this introductory collection of real specimens of metamorphic rock. Metamorphic rocks are formed by pressure and heat that may or may not be influenced by the introduction of chemically active solutions - they are an example of how pressure and heat, typically associated with destructive forces, can yield creation; examples include schist, serpentine, and quartzite. The Metamorphic Rock Bag is an economy collection of 6 specimens representative of the metamorphic rock family. Each generous specimen is 1.25" to 1.5" and is contained in a zip lock bag with a label.
