前言于板块的会聚边界处,通常海洋板块发生俯冲,可是在该处若碰上大陆及其断块,或海台和海山等就发生所谓“碰撞”现象。在历史上曾发生过不同规模的碰撞,例如印度板块向欧亚板块的碰撞、伊豆半岛向本州的碰撞等,目前,碰撞运动仍在继续进行。如果说这些碰撞对它们所在区域的大地构造有巨大作用的话,那么对俯冲的板块也有影响。关于板块运动的原动力尚在进行着各种研 Foreword At the converging boundary of the plate, the subduction of the ocean plate usually occurs. However, a so-called “collision” occurs if the mainland and its fault blocks hit the sea or seamounts and seamounts. There have been collisions of different scales in history, such as the collision of the Indian Plate with the Eurasian Plate and the collision of the Izu Peninsula with the Honshu region. At present, the collision movement is still going on. If these collisions had a huge effect on the geotectonic structure of their area, then they also had an effect on subducted plates. Motivation for plate movement is still undergoing various studies
