The formation of abyssal serpentinites leads to deep changes of the oceanic lithosphere rheology and geochemistry, hence playing a key role on geodynamic and geochemical cycles. Here we review and discuss the geochemical diversity of serpentinites collected on abyssal floors (i.e., abyssal serpentinites) from different geodynamical settings, namely passive margin, forearc and oceanic spreading ridges. We further divided abyssal serpentinites from spreading ridges according to the tectonic contexts in which they were exhumed, differentiating slow-spreading centres (exhumed within the axial valleys and at oceanic detachments), ultra-slow spreading centres (from amagmatic axial valleys and smooth seafloor), fast spreading axis (mostly from deeps) and large transform faults (all spreading rates).

深海蛇纹岩地球化学与地球动力学研究进展


深海蛇纹岩的形成导致海洋岩石圈流变学和地球化学的深刻变化，因此在地球动力学和地球化学循环中起着关键作用。在这里，我们回顾和讨论了从不同地球动力学环境（即被动边缘、前弧和海洋扩张脊）收集的深海蛇纹岩（即深海蛇纹岩）的地球化学多样性。我们根据深海蛇纹岩被挖掘的构造环境进一步划分了它们与扩张的山脊，区分了缓慢扩散的中心（在轴向山谷和海洋分离处挖掘出来）、超慢扩张中心（来自岩浆般的轴向山谷和光滑的海底）、快速扩张轴（主要来自深处）和大型转换断层（所有扩张速率）。
