中文摘要
该研究将提供三维结构的更高分辨率,并首次获得慢扩张脊下地壳/上地幔结构的三维图像。结果将限制岩浆管道模型。该项目需要一些技术发展,以最好地结合广角反射和折射数据,并将提供对脊热结构的三维性质的见解,任何深部地壳或地幔岩浆储层的存在,沿脊岩浆供应的可变性,以及深部与浅层岩浆沿轴输送的重要性。
英文摘要
This study will provide improved resolution of 3D structure and the first 3D images of lower crustal/upper mantle structure beneath a slow-spreading ridge. The results will constrain models of magma plumbing. The project requires some technique development to best combine the wide-angle reflection and refraction data, and will provide insights into the 3D nature of the ridge thermal structure, the existence of any deep crustal or mantle magma reservoirs, the variability in magma supply along the ridge, and the importance of along-axis transport of magma at deep versus shallow levels.
