Concept information
TERME PRÉFÉRENTIEL
VOLCANIC DEPOSITS
DÉFINITION
- Volcanic deposits (including volcanic ash, debris, etc.) are found within ice core records. Volcanoes can produce large quantities of particles and leave a record in the ice. Scanning electron micrographs of the particles from a particularly large dust peak in an ice core may reveal that it is from a known volcano and allow a firm date to be placed on that section of core. For prehistoric times, the dust record is a key tool for reconstructing a history of volcanic activity.
