  • Augite, Raw Mineral Specimens, Approx. 1", PK12
    Item #:
    23A00X718

    Augite is a common rock-forming pyroxene mineral that forms as magma is cooling. It is an imperative sample for lessons on Bowen's reaction series Augite's perpendicular planes of cleavages make it an excellent tool for studying 2-plane, 90° cleavage Each specimen is selected and hand processed,...

  • Siltstone, Raw Sedimentary Rock Specimens, Approx. 1", PK12
    Item #:
    23A00X746

    Pack of 12 Siltstone samples approximately 1" (3cm) in size Clastic sedimentary rock made up of fine silt particles Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Good sample for use in identifying...

  • Biotite, Raw Mineral Specimens, Approx. 1", PK12
    Item #:
    23A00X719

    Found within igneous and metamorphic rocks. Biotite mica's sheet like appearance and glassy luster make this mineral easy to identify Mica's thin and layered structure is perfect for demonstrating variable hardness and cleavage, physical properties of minerals, as well as Bowen's reaction series....

  • Pink Granite, Raw Igneous Rock Specimens, Approx. 1", PK12
    Item #:
    23A00X752

    Commonly found as magmatic intrusions in the crust, granite forms slowly in shallow or evolved magma chambers. The large crystals are indicative of a slow cooling rate, and make mineral identification simple Ideal for identification & classification exercises. This classic igneous rock is a...

  • Anthracite Coal, Raw Metamorphic Rock Specimens, Approx. 1", PK12
    Item #:
    23A00X759

    Anthracite coal is bright and reflective, indicative of the intense heat and pressure required to form it. Anthracite coal often has a favorable purity ratio, containing mostly organic material and relatively few impurities Ideal for identification & classification exercises. Allows students can get...

  • Olivine, Raw Mineral Specimens, Approx. 1", PK12
    Item #:
    23A00X730

    Much of the earth's surface is covered in oceanic crust, of which olivine is a major component. With the highest crystallization temperature, olivine is the first mineral to form in a magma, making it a useful geothermometer Ideal for identification & classification exercises, and is great for...

  • Galena, Raw Mineral Specimens, Approx. 1", PK12
    Item #:
    23A00X722

    Galena grows in beautiful metallic cubes. Often refined as lead ore, galena can also be used to teach students about a mineral's luster, streak, and cleavage. Because of the lead in the chemical formula, it is much denser than other minerals, which makes it seem unnaturally heavy for its size Ideal...

  • Limestone Chalk, Raw Sedimentary Rock Specimens, Approx. 1", PK12
    Item #:
    23A00X739

    Limestone is made up of organic material, primarily calcium carbonate. The chalk variety consists of the shells of coccolithophores, small platy animals that stack together and powder easily. Large layers of chalk indicate a low-oxygen environment, most likely ancient seafloor beds Ideal for...

  • Sulfur, Raw Mineral Specimens, Approx. 1", PK12
    Item #:
    23A00X733

    Pack of 12 Sulfur samples approximately 1" (3cm) in size Great for students learning about streak tests - sulfur leaves an unexpected white streak Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Ideal for...

  • Sphalerite, Raw Mineral Specimens, Approx. 1", PK12
    Item #:
    23A00X782

    Pack of 12 Sphalerite samples approximately 1" (3cm) in size Often mined as a zinc ore Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Sphalerite sometimes exhibits triboluminescence, meaning it will glow...

  • Gray Limestone, Raw Sedimentary Rock Specimens, Approx. 1", PK12
    Item #:
    23A00X740

    The massive, gray variety of limestone is often found deposited in marine environments. It is made up of organic material, primarily calcium carbonate Excellent for demonstrating the tendency of calcium carbonate to effervesce in acid, and is perfect for identification and classification exercises....

  • Pegmatite, Raw Igneous Rock Specimens, Approx. 1", PK12
    Item #:
    23A00X788

    Pack of 12 Pegmatite samples approximately 1" (3cm) in size Igneous rock containing a large variety of crystal sizes Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements Pegmatite indicates two different periods...

  • Talc, Raw Mineral Specimens, Approx. 1", PK12
    Item #:
    23A00X734

    Through the process of metasomatism, hot fluid infiltrates the atomic structure of other silicate minerals, altering them to form talc. Talc is at the bottom of the Mohs scale of hardness, and has a distinct soapy feel Ideal for identification & classification exercises. A great example for lessons...

  • Obsidian, Raw Igneous Rock Specimens, Approx. 1", PK12
    Item #:
    23A00X753

    Obsidian, also known as volcanic glass, forms from lava that cools almost immediately upon eruption, usually into water Obsidian shares many physical properties with its major chemical component, quartz, despite looking dissimilar - great for classification exercises. This set of twelve samples is...
