摘要

采用仪器中子活化分析法测定了各种地质样品中20多个元素的含量。为了检验方法的准确度和精密度，分析了美国国家地质局的标准物质USGS-AGV-I、USGS-BCR-1及美国国家标准局的NBS-1632煤粉，准确度和精密度的误差均小于15%。

用仪器中子活化分析法测定了日喀则蛇绿岩中稀土元素含量，通过对稀土元素地球化学特征的分析，我们认为日喀则蛇绿岩在地球化学性质方面相似于大洋中脊拉斑玄武岩，它们可能是形成于特提斯洋脊。

Abstract

It has been shown that the instrumental neutron activation analysis can be used todetermine 20 elements in geological samples. Precision and accuracy of the INAA method have been evaluated by USGS and NBS standard reference materials. The errors in precision and the accuracy are less than 15%.

The abundance of REE elements has been determined in representive samples from the Rikezhe ophiolite complex. The result indicates that the ophiolitic lavas are geochemically similar to the mid-ocean ridge tholeiites

and they are possibly volcanic eruptive products during the process of the Tethyan mid-ocean ridge spreading.
