通过对中国东北镜泊湖玄武岩中气体组分的测量,分析了不同温度状态下气体组分之间的关系及气体的含量,对地幔原始气体的地球化学特征提出了一些初步的看法。认为:地幔流体中有大量的气体组分,气体组分通过岩浆作用或地下构造作用等运移到地壳中的适当部位可以形成幔源气藏;对原始地幔中气体组分的了解有助于我们了解这些幔源气藏的形成及地球化学特征。
By measuring the gas composition of the Jingbo Lake basalts in northeastern China, the relationship between the gas components and the gas content under different temperature conditions has been analyzed. Some preliminary opinions on the geochemical characteristics of the original mantle gas have been put forward. It is considered that there are a large number of gas components in the mantle fluid, and the gas components can migrate to appropriate sites in the crust through magma or underground tectonics to form mantle source gas reservoirs. Understanding of the gas components in the original mantle contributes We understand the formation and geochemical characteristics of these mantle source gases.
