Pb-Pb and trace element analyses of detrital feldspars from sediment core IN2017_V01-A042-KC14 and in-situ feldspars from coastal rocks of Chick Island and Balaena Islets, East Antarctica

Pb-Pb ratios, ages and trace element data from detrital feldspars in kasten core IN2017_V01-A042-KC14 from the continental slope of central Wilkes Land, East Antarctica and in-situ feldspars from coastal basement rocks in East Antarctica (Chick Island and Balaena Islets). All data was obtained using laser ablation-inductively-couple plasma mass spectrometry (LA-ICPMS). All ratios and ages are shown with one standard error.

本数据集涵盖两类样品的分析数据：一是采自东南极洲威尔克斯地中部大陆坡箱式岩心（kasten core）IN2017_V01-A042-KC14的碎屑长石，其分析数据包括铅-铅同位素比值、定年年龄及微量元素含量；二是采自东南极洲沿海基底岩床（奇克岛与巴莱娜群岛）的原位长石分析数据。所有数据均通过激光剥蚀-电感耦合等离子体质谱法（LA-ICPMS）获取，所有比值与定年年龄均标注了一倍标准误差。
