Editorial Review
Ash and dust deposited during explosive volcanic eruptions can eventually become compacted and lithified, forming large packages of tuff. These tuff layers leave a record of the size and intensity of the volcanic eruption, and are used by geologists to estimate rate of activity. This sample is perfect for exercises in igneous rock classification.
Features
1) Twelve volcanic tuff samples approximately 1" (3cm) in size
2) Sample from a compacted ash layer deposited during a gaseous, explosive eruption
3) Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements
4) Distinct layers within tuff indicate separate eruption pulses or events
5) Specimen comes in clear labeled and barcoded bag for ideal storage
