资源简介:

Analytical details:(a) All reported 143Nd/144Nd ratios are corrected to a Rennes value of 0.511961 (Chauvel & Blichert-Toft, 2001, doi:10.1016/S0012-821X(01)00379-X).(b) S.E. = internal precision (2s level) on sample measurement(c) εNd based on present-day CHUR value 143Nd/144Nd = 0.512638 expressed in parts per 10,000 (Jacobsen and Wasserburg, 1980, doi:10.1016/0012-821X(80)90125-9).(d)External error based on the reproducibility of all Rennes standards measured during run. (e) 147Sm/144Nd ratio calculated from direct measurements and an average value from the measured samples at the site.(f) εNd (t) were calculated using values from column (e) and CHUR values of 143Nd/144Nd 0.512638 and Sm/Nd 0.1966 from Jacobsen and Wasserburg (1980, doi:10.1016/0012-821X(80)90125-9).
