Shale - Carbonaceous Specimen, ±1" in size, Each

Details

Here is the corrected text: Raw Carbonaceous Shale Specimen - Single Sample, 1" Shale forms from the cementation and lithification of very small grains of rock, commonly mud or clay. The black color of this rock indicates an organic-rich composition. Black shale can contain trace amounts of oil, which is why it is studied heavily. Shale is useful in sedimentary rock identification exercises due to its recognizable fissile habit. While each specimen will vary slightly in shape, size, and color, it will measure approximately 1" in length. Each is individually packaged, 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.
