Hornblende (Amphibole Mineral) Specimen, Each

Details

Here is the corrected text: Hornblende is part of a group of minerals known as amphiboles, which are chemically and structurally similar to pyroxenes but include water in their atomic structure. Great for geology classrooms, hornblende is ideal for identification and classification exercises. It's particularly useful when studying both igneous and metamorphic rocks, as well as the process behind mineral identification. Each specimen is selected and hand-processed by an actual geologist, ensuring that each sample exhibits defining features. Our rock and mineral samples are sourced from a variety of locations around the world and processed in Victor, NY. Each specimen sample is packaged in a transparent bag and labeled and barcoded for easy identification. This raw hornblende specimen is approximately 1" in length. Its perpendicular planes of cleavage make it an excellent tool for studying 2-plane, 90° cleavage. While each specimen may vary slightly in shape, size, and color, every sample is individually packaged, labeled, and barcoded for easy identification and storage. Selected and processed by a geologist, each specimen is hand-picked to ensure that it exhibits defining features. Our rocks and minerals are sourced from around the world and processed by hand in Victor, NY. Technical support is always available; feel free to reach out to our team of scientists and geologists for additional information or assistance with any questions regarding our rock and mineral samples.
