Zircon U-Pb-Hf and whole rock 142 isotope data from the Slave craton

Abstract: This dataset shows the age of meta-igneous rocks from the Slave craton, rocks which are part of the Archean basement gneiss complex. The ages and eHf values were measured by laser ablation split stream measurements, and the 142Nd isotope compositions were measured by TIMS.

摘要：本数据集涵盖奴隶克拉通（Slave craton）内变质火成岩的年龄数据，该类岩石属于太古宙基底片麻岩杂岩。其年龄与εHf值通过激光剥蚀分流测量法测定，142Nd同位素组成则借助热电离质谱（TIMS, Thermal Ionization Mass Spectrometry）完成测试。
