Deep seismic data and plate kinematic reconstructions help understand the mechanisms of rifting and opening of new oceans, basic principles of plate tectonic cycles. In this study, available deep wide-angle seismic velocity models from the Atlantic margins are reviewed and plate reconstructions used to define conjugate model pairs. The main objective was to study the question of how magma-rich and magma-poor margins develop and the role of inheritance in the break-up. We also studied the question of the mechanism of formation and the origin of transform marginal plateaus, which are typically found at the border of two ocean basins of different ages and are mostly characterized by at least one volcanic phase during their formation. The results of the study include the comparison of crustal thickness, oceanic plate thickness and the influence of volcanism along the Atlantic margins. The conjugate profiles image different degrees of asymmetry of the Atlantic Margin rifts. Marginal plateaus might form when rifting stops at barriers leading to the accumulation of heat in the mantle and increased volcanism directly before or after halting of the rifting.

深层地震数据和板块运动学重建资料有助于理解新海洋裂谷和开裂的机制，以及板块构造周期的基本原理。在这项研究中，对来自大西洋边缘的深层广角地震速度模型进行了回顾，并利用板块重建来定义共轭模型对。主要目的是研究富浆岩浆边缘和贫浆岩浆边缘如何发展以及继承在分裂中的作用。我们还研究了转换边缘高原的形成机制和起源的问题，这些边缘高原通常出现在两个不同年龄的海盆的边界，并且在其形成过程中大多具有至少一个火山相。研究结果包括地壳厚度的比较，海洋板块厚度和火山活动沿大西洋边缘的影响。共轭轮廓反映了大西洋边缘裂谷的不同程度的不对称性。当裂谷停止在屏障处时，边缘地势可能会形成，导致热量直接在裂谷停止之前或之后在地幔中积聚并增加火山活动。
