Abstract: | We have alternately measuredNd isotopic ratios for JNdi-1,newly issued by the Geological Survey of Japan, and La Jolla. The results of 13 analyses are follows;JNdi-1:143Nd/144Nd = 0.5121003土0.0000104 (SD: standard deviation); 142Nd/144Nd=1.141846± 0.000031 (SD); 145Nd/144Nd=0.3484038 ± 0.0000089 (SD) and La Jolla: 143Nd/144Nd=0.5118455 ± 0.0000069 (SD); 142Nd/144Nd=1.141843 ± 0.000047 (SD); 145Nd/144Nd = 0.3484007 ± 0.0000041 (SD). The mean value of 143Nd/144Nd ratio for JNdi-1,normalized to the proposed value of La Jolla (0.511858) is 0.512113, which agrees well with a previous cbtermination (0.512119) by Tanaka et al. (1996). |
