Lead and neodymium isotope time-series for manganese crust D137-01

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...年龄通过由10Be/9Be比值（10Be/9Be ratios）推导得到的生长速率，结合恒定钴通量（Co-flux）模型计算得出。为保证兼容性，所有比值均被标准化至Galer等人所采用的NIST SRM981标准值...
