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米深度处、公元前约1628年的隐火山碎屑的玻璃组分性质相关数据。相关测试由缅因大学的Cameca SX1000型电子探针显微分析仪完成。本次颗粒化学组分测试的开展目的为火山碎屑年代学研究。
