马尼拉海沟南端的形态和构造研究表明，南中国海盆和吕宋岛之间的汇聚因俯冲板块的性质而异，洋壳俯冲时，形成了简单的增积棱柱-弧前盆地格局。相反，在盆地大陆边缘被俯冲的地方，板内变形随机分布在弧前区的主要部分，该地区被碎裂为各种地壳微块体。在POP2巡航期间，在这一俯冲-碰撞过渡带进行的海束测绘和详细的地球物理测量的结果，与RV。“Jean Charcot”在这里被提出和讨论，使我们对这种俯冲-碰撞过渡带的机制有了新的认识。
The morphological and structural study conducted at the southern tip of the Manila trench, reveals that convergence between the South China Sea basin and Luzon is accommodated differently depending on the nature of the subducted slab.When the oceanic crust is subducted, a simple accretionary prism-fore arc basin pattern is developed. Conversely, where the continental margin of this basin is subducted, intraplate deformation is randomly distributed across the major part of the fore arc area which is fragmented into various crustal microblocks. Results of seabeam mapping and detailed geophysical surveying conducted at this subduction-collision transition zone, during the POP2 cruise, with R.V. “Jean Charcot” are presented and discussed here and allow us a new insight into the mechanism of such a subduction-collision transition zone.
