Gypsum Mineral Specimen, Gypsum Mineral Specimen ideal for use in study of cleavage and fracture as example of imperfect cleavage planes., Pack of 12

Details

Here is the corrected text: Gypsum: A sulfate mineral that often forms from evaporating lakes, known as an evaporite deposit. Crystals grow into soft, wide sheets, but gypsum is also commonly found filling veins and fractures in other rocks. This set of six samples is great for geology classrooms. Gypsum is one of the standards on the Mohs hardness scale, and its similar appearance to other minerals makes it useful in identification exercises. Each specimen is selected and hand-processed by an actual geologist, ensuring each sample exhibits defining features. Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY. The set is packaged in a transparent bag and is labeled and barcoded for easy identification. Raw Gypsum Specimen Set of 12 Samples, 1". A sulfate mineral that often forms from evaporating lakes, known as an evaporite deposit. Crystals grow into soft, wide sheets, but gypsum is also commonly found filling veins and fractures in other rocks. Ideal for identification and classification exercises. Gypsum's perpendicular planes of cleavage make it an excellent tool for studying 2-plane, 90° cleavage. While each specimen will vary slightly in shape, size, and color, it will measure approximately 1" in length. The set is packaged in a transparent bag, labeled and barcoded for easy identification and storage. Selected and Processed by a Geologist: Each and every specimen is selected and hand-processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.
