Lead and neodymium isotope time-series for manganese crust SO36-63KD

Ages were calculated using growth rates derived by 10Be/9Be ratios and constant Co-flux model. For compatibility all ratios were normalized to the NIST SRM981 values of Galer...本数据集的年龄计算采用基于10Be/9Be比值（10Be/9Be ratio）推导得到的生长速率，并结合恒定钴通量模型（constant Co-flux model）完成。为保证可比性，所有比值均已归一化至Galer等人报道的美国国家标准与技术研究院（National Institute of Standards and Technology, NIST）SRM981标准参考物质的数值……
