Raw Volcanic Tuff Specimen
Set of 12 Samples, 1″

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 1″ 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.
