Raw Argillaceous Shale, Sedimentary Rock Specimen, ± 1"

• ARGILLACEOUS SHALE | Shale is formed from the cementation and lithification of very small grains of rock, commonly mud or clay. The small clast size indicates that though the grains had been heavily eroded, the rock formed in a low energy environment
• GREAT FOR GEOLOGY CLASSROOMS | Ideal for sedimentary rock identification & classification exercises due to argillaceous shale's recognizable fissile habit
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Rochester, NY
• LABELED PACKAGING | Samples are packaged in a transparent bag, labeled & barcoded for easy identification

Raw Argillaceous Shale Specimen
Single Sample, 1"

Shale is formed from the cementation and lithification of very small grains of rock, commonly mud or clay. The small clast size indicates that though the grains had been heavily eroded, the rock formed in a low energy environment. Ideal for sedimentary rock identification & classification exercises due to argillaceous shale's recognizable fissile habit.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Specimen is packaged in a transparent bag that is labeled & barcoded for easy identification and storage.

Selected & 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 Rochester, NY.
