Raw Volcanic Tuff, Igneous Rock Specimen - Hand Sample, ± 2.75"

• VOLCANIC TUFF | Dust & ash deposited during explosive volcanic eruptions can become compacted and lithified over time, forming large packages of tuff. These layers show a record of the eruptions size & intensity, and allow geologists to estimate the rate of activity
• GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises
• 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 Victor, NY
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

Raw Volcanic Tuff Specimen
Single Sample, 3"

Dust & ash deposited during explosive volcanic eruptions can become compacted and lithified over time, forming large packages of tuff. These layers show a record of the eruptions size & intensity, and allow geologists to estimate the rate of activity. Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises.
While each specimen will vary slightly in shape, size and color, it will measure approximately 3" in length. Each is individually packaged, 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 Victor, NY.
