The breakup of continents is fundamental to the creation of the Earth’s surface and oceans but many aspects remain poorly understood. Breakup involves a complex interplay of extensional tectonics and magmatism, 形成了一系列裂谷边缘类型, including a “magma-poor” end-member involving broad regions of exhumed and serpentinised (hydrated) mantle. Breakup at such margins is commonly followed by slow to ultra-slow seafloor spreading, which can also result in mantle exhumation and thus ambiguity about where seafloor spreading starts. Normal faulting plays a key role in supplying fluids driving serpentinisation beneath hyper-extended continental crust but its role in regions of exhumed mantle is less clear. 为了解决这些问题, we will image lateral variations in serpentinisation and magmatism at the Goban Spur margin southwest of the UK by acquiring the first controlled source electromagnetic (CSEM) dataset across a continent-ocean transition (expected summer 2023), 使用拖曳式和海底接收器. We will also detect differences between underlying continental and oceanic mantle using passive electromagnetic (magnetotelluric) data. 学生将分析该数据集的一个子集, guided by results from a wide-angle seismic survey acquired during the same cruise and extensive pre-existing multichannel reflection data along the same profiles and nearby.
