Eoarchean rocks from the Isua region in southern West Greenland are known to exhibit isotope anomalies of W-182 and Nd-142. The excess W-182 in many rocks from the Isua region have been explained by two endmember models: (1) missing late veneer or (2) silicate differentiation shortly after Earth...
