Scoria Specimen, Scoria forms when spatter from bubbly mafic lava cools quickly., Pack of 12

Details

Here is the corrected text: Scoria forms when bubbly, mafic lava spatter is thrown into the air and cools quickly. The rapid crystallization process traps large air pockets within the rock, often giving samples a jagged, sharp appearance. This set of twelve scoria specimens is great for geology classrooms, providing an excellent example of pyroclastic material that can be used in various igneous classification exercises. Each specimen is ideal for group study and examination. Selected and hand-processed by an actual geologist, each sample exhibits defining features. Our rock and mineral samples are sourced from locations around the world and processed locally in Victor, NY. Each scoria specimen is individually packaged in a transparent bag, labeled, and barcoded for easy identification. While specimens may vary slightly in shape, size, and color, they measure approximately 1 inch in length. Technical Support: Our team of scientists and geologists is always available to provide additional information or assist with any questions regarding our rock and mineral samples.
