Glass properties of ~1628 BCE cryptotephra from 774.53-774.78m depth of the GISP2 ice core

Glass properties of ~1628 BCE cryptotephra extracted from 774.53-774.78m depth of the GISP2 ice core. Measurements were collected with Cameca SX1000 at the University of Maine. Particle chemistry measurements were collected for the purpose of tephrochronology.

本数据集涵盖取自GISP2冰芯774.53~774.78米深度、年代约为公元前1628年的隐火山碎屑（cryptotephra）的玻璃性质数据。相关测试数据由缅因大学使用Cameca SX1000型仪器采集获取。本次颗粒化学组分测试的开展旨在服务于火山碎屑年代学（tephrochronology）研究。
