Glass chemistry of cryptotephra extracted from 23.61-23.69m depth of South Pole Ice Core

Glass chemistry of cryptotephra grains extracted from the 23.61-23.79m depth interval of the South Pole Ice Core (Antarctica). Measurements were collected using SEM-EDS on individual grains. Measurements were collected to characterize the identified tephra deposit at this depth for the purpose of tephrochronology.
