这项研究将提高3D结构的分辨率,并首次提供缓慢扩张的山脊下的下地壳/上地幔结构的3D图像。这一结果将限制岩浆管道的模型。该项目需要一些技术开发,以最好地结合广角反射和折射数据,并将提供对山脊热结构的三维性质、是否存在任何深部地壳或地幔岩浆储藏、沿山脊的岩浆供应的可变性以及深部与浅层岩浆沿轴向输送的重要性的深入了解。
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.
