通过近年来对藏北地区地质工作的进一步开展,发现该地区有一套典型的水下喷发玄武岩,具枕状构造和球颗构造。为了进一步阐明其岩名的成因、我们采集了一些枕状玄武岩的样品,用中子活化分析方法研究了玄武岩中的稀土元素及其有关的微量元素。本文仅对分析结果和初步的解释作一简要介绍。
Through the further development of geological work in northern Tibet in recent years, it is found that there is a typical underwater eruptive basalt in the area with pillow-shaped structure and spherical structure. In order to further elucidate the origin of rock names, we collected some samples of pillow-shaped basalt and studied the rare earth elements and their related trace elements in basalt by neutron activation analysis. This article only gives a brief introduction of the analysis results and preliminary explanations.
