Product Overview

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.
