Concept
Enrichment with respect to 143Nd/144Nd in the CHondritic Uniform Reservoir (CHUR) of neodymium-143 {143Nd CAS 14336-83-5} {epsilon(143)Nd} in the water body [dissolved plus reactive particulate phase] by thermal ionization mass spectrometry

| Definition | The isotopic enrichment of 143Nd is calculated using the epsilon notation defined as epsilon Nd =([143Nd/144Nd] sample / [143Nd/144Nd] CHUR-1) x 10000). One epsilon unit represents a one part per 10,000 deviation from the CHUR composition. |
