高纬度北大西洋地幔放射成因同位素成分ＤｉｅｔｅｒＦ．Ｍｅｒｔｚ等冰岛熔岩以及周围上地幔熔岩的成因一直令人争执不休。为解释冰岛上观察到的同位素趋势，有人提供了一个丰富的地幔羽源与衰竭的洋中脊玄武岩（ＭＯＲＢ）源或衰竭的地幔羽源的混合过程。在本文中，冰岛... Radiogenic isotope composition of high latitude mantle in the North Atlantic. The causes of Icelandic lava, such as Mertz, and the surrounding upper mantle lava have been disputed. In order to explain the observed isotopic trends in Iceland, it was provided a rich mixture of mantle plumes and depleted mid-ocean basalts (MORB) or depleted mantle plumes. In this article, Iceland ...
