The methods used for precise calibrations of Sm/Nd ratios and the average isotopic abundances obtained for normal Sm and Nd are given. A mixed Sm-Nd normal solution with a precisely known ^(147)Sm/^(144)Nd ratio close to the nominal average chondritic value is described and the calibration discussed. Aliquots of this standard solution are available on request and may be useful for precise interlaboratory calibration of Sm and Nd.

Additional Information:© 1981 Pergamon Press Ltd. Received 17 March 1981; accepted in revised form 21 July 1981. This work has been supported by NSF grant EAR 76-22494 and NASA grant NGL 05-002-188. We wish to thank L. NYQUIST for a very thorough review of this paper which resulted in several substantial improvements. We also thank R. K. O'NIONS for his review of this paper and his genuine concern for interlaboratory standards. A third anonymous reviewer who thought that the paper should not be published is thanked for making us aware that the "seemingly rigorous attention to detail in the described procedures" which are here presented "is probably common practice in laboratories involved in this type of work". We thank G. LuGMAIR for sending us a La Jolla Nd isotope standard and for discussing his views on Nd isotope analysis with us. Support for some of the time and computing necessary for writing this paper was obtained from the Committee on Experimental Geology and Geophysics at Harvard.
