摘要

应用中子活化分析法对河南南阳独山玉的稀土微量元素进行了研究

结果表明 :白独玉、绿独玉与黑独玉的地球化学特征有明显的差别。其中

它们每种玉的平均值 :8个稀土总量（8∑REE）分别为 1.4 5、6 .895、3.86 7μg·g- 1;全线斜率（La/Yb）分别为 14 .2 77、4 .936、0 .84 9μg·g- 1;微量元素Sr分别为 75 4、4 34、115 μg·g- 1

Cr分别为 5 .5 3、10 95、85 1μg·g- 1

Fe分别为 2 777、2 838、2 875 0 μg·g- 1

Mn分别为 6 8、6 5 .5、5 32 μg·g- 1;绿独玉正Eu异常最大

而黑独玉的正Eu异常最小。这些特征可作为鉴别独山玉的地球化学标志

对考古及古玉的深入研究与鉴别具有重要意义。

Abstract

The geochemical features of different types of Dushan jade are differentiated based on trace element and REE geochemistry using neutron activation analysis (NAA). For white

green and black Dushan jade

the ∑REE values are 1.45

6.895 and 3.867μg/g respectively; La/Yb 14.277

4.936 and 0.849; Sr contents 754

434 and 115μg/g; Cr contents 5.53

1095 and 851μg/g; Fe contents 2777

2838 and 28750μg/g; Mn contents 68

65.5 and 532μg/g

separately. There is the highest positive Eu abnormity in the green Dushan jade and the lowest positive Eu abnormity in the black Dushan jade. These characteristics are of important significance for both deep study and discrimination on ancient jade.
