Further details and definitions: εNd : epsilon Nd following the equation : εNd = ((143Nd/144Nd)sample/(143Nd/144Nd)CHUR - 1) * 10,000 . The unit should be "per ten thousand" but...
进一步的细节与定义如下：εNd（epsilon Nd）遵循下述计算公式：εNd = [(¹⁴³Nd/¹⁴⁴Nd)试样 / (¹⁴³Nd/¹⁴⁴Nd)球粒陨石均一储库（Chondrite Uniform Reservoir, CHUR） - 1] × 10000。其单位本应为"万分之一"，但……
