Nd and Sr isotope compositions of debris from the basal ice of the Byrd ice core, central West Antarctica

This dataset comprises of Nd and Sr isotope compositions of debris melted from three intervals of basal ice from the Byrd ice core. Measurements were performed on the <75 micron fractions, both with and without treatment in a leaching solution designed to remove authigenic coatings, as well as a rhyolite cobble. The ice core the debris was extracted from was drilled at 80° 0.1'S, 119° 31.0'W at Byrd Station, West Antarctica, in January 1968.本数据集包含从伯德冰芯（Byrd ice core）三处底部冰段熔融产生的碎屑的钕（Nd）与锶（Sr）同位素组成数据。相关测量针对粒径小于75微米的组分开展，分别经用于去除自生涂层的浸取液处理与未经处理两种工况，同时对一块流纹岩砾石进行了测量。该碎屑提取自的冰芯于1968年1月在南极洲西部伯德站以80°0.1′S、119°31.0′W的坐标完成钻探。
