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. Prior to the release date, data and IGSN metadata are available upon request from corresponding author Andrei Kurbatov ([e-mail]).

取自南极冰芯（South Pole Ice Core, Antarctica）23.61–23.79米深度层位的隐火山灰（cryptotephra）颗粒的玻璃相化学组成数据。本次测试采用扫描电子显微镜-能谱仪（SEM-EDS）对单颗粒进行分析并采集数据，旨在表征该深度层位已识别的火山灰沉积，以服务于火山灰年代学（tephrochronology）研究。在正式发布日期前，数据集内容及国际地质科学编号（IGSN）元数据可向通讯作者Andrei Kurbatov（[e-mail]）申请获取。
