| 摘 要： | <正> 黄汲清教授(1979)在研究板块构造演化模式时曾经强调指出:板块构造是长期的、多阶段发展的,也就是说是多旋回发展的。它包括多旋回构造运动(板块俯冲、褶皱造山),多旋回沉积建造,多旋回岩浆活动(花岗岩、火山岩等)以及多旋回找矿作用。南海及其周缘的地质构造就是板块构造多旋回发展的一个实例。本文试图根据南海及周缘地区的地质地球物理调查成果,对其新生代(包括晚白垩世)的多旋回构造作一简要概述。

| Abstract: | The South China Sea structures have resulted from the evolution of the polycyclic plate tectonic movements.During the Cenozoic (including the Late Cretaceous), the South China Sea underwent plate tectonism of three cycles of Late Cretaceous-Eocene, Oligocene-Miocene, Pliocene-Pleistocene, resulting in the Philippine-Borneo orogenic zone that is characterized by polycyclic magmatic activities, sedimentary buildups, and folding and,faulting,and the Celebes, Sulu and South China Sea, and the West Zhongsha and Nansha continental fragments which underwent polycyclic spreading.The Cenozoic tectonics in the South China Sea shows that a complete plate tectonic cycle consists of six stages including crustal rifting, sea-floor spreading, plate drifting, plate convergence, plate subduction, and plate collision. The former three ones aresea-making movements and the latter ones are orogenic movements. These two kinds of movements are the different representations of geodynamics in the plate tectonic cycles; the sea-making areas and orogenic zones are the products of different periods in the plate tectonic cycles. |
