抽象的。东亚巴拉望微大陆块体是早中新世以来与地震活跃的菲律宾移动的带发生碰撞的海洋测深高。因此，构造微块紧北（吕宋岛）和南部（西米沙鄢块）的碰撞前旋转在相反的意义。旋转导致微块体进入邻近的走滑断层，并将其转换为俯冲带，即目前的马尼拉和内罗毕海沟。此外，这次碰撞还引发了主要的左旋走滑断层、菲律宾断层带和菲律宾海沟的向南传播，菲律宾海沟沿着菲律宾群岛的东部边界界定了菲律宾群岛。根据陆上和海上数据，菲律宾断层带和东吕宋海槽-菲律宾海沟似乎也向北扩展。此外，还注意到马尼拉海沟和内海海沟的传播方向相反，分别从菲律宾中部的碰撞地点向其北方和南方延伸。马尼拉海沟（早中新世），菲律宾断层带（中中新世）和菲律宾海沟（上新世）的起始年龄与菲律宾中部沿着由西向东的断面的碰撞和随后的巴拉望与菲律宾移动的带的其余部分的缩进一致。
Abstract. The aseismic Palawan microcontinental block is an oceanic bathymetric high that has collided with the seismically‐ac‐tive Philippine Mobile Belt since the Early Miocene. Consequently, tectonic microblocks immediately north (Luzon) and south (Western Visayas Block) of the collision front rotated in opposite senses. The rotation led the microblocks to onramp adjacent strike‐slip faults, and converted these to subduction zones, namely, the current Manila and Negros Trenches. In addition, the collision also initiated the southward propagation of a major left‐lateral strike slip fault, the Philippine Fault Zone, and the Philippine Trench, which bounds the Philippine archipelago along its eastern boundary. Based on onshore and offshore data, the Philippine Fault Zone and the East Luzon Trough ‐ Philippine Trench appears to also propagate northward. Furthermore, the opposite direction of propagation is also noted for the Manila and Negros Trenches from the locus of the collision in the Central Philippines to their northern and southern extensions, respectively. The ages of initiation of the Manila Trench (Early Miocene), Philippine Fault Zone (Middle Miocene) and Philippine Trench (Pliocene) as encountered along a west to east transect in the Central Philippines are consistent with the collision and subsequent indentation of Palawan with the rest of the Philippine Mobile Belt.
