太古宙基性岩、TTG 和富钾花岗岩的铁同位素分析数据

本数据为太古宙华北克拉通变玄武岩、TTG和富钾花岗岩的Fe同位素数据。样品采集自冀东、鲁西和辽西地区。Fe同位素分析测试是在中国地质大学（北京）同位素地球化学实验室完成，利用多接收电感耦合等离子体质谱仪（MC-ICP-MS）和标样-样品间插法/双稀释剂法进行质量歧视校正获得。通过对获得的全岩Fe同位素数据进行系统研究，能够帮助了解来自不同源区的岩浆岩Fe同位素特征和分馏机制，可以帮助对比古老克拉通和现代地幔和地壳的异同。

This dataset contains Fe isotope data of Archaean metamorphic basalt, TTG and high-potassium granite from the North China Craton. Samples were collected from eastern Hebei, western Shandong and western Liaoning regions. Fe isotope analyses were conducted at the Isotope Geochemistry Laboratory of China University of Geosciences (Beijing), with mass discrimination correction performed using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) combined with the standard-sample bracketing method and double spike method. Systematic research on the acquired whole-rock Fe isotope data can help clarify the Fe isotope characteristics and fractionation mechanisms of magmatic rocks from different source regions, and facilitate comparative studies on the similarities and differences between ancient cratons and modern mantle and crust.
