摘要:
中国东部中—新生代构造活动主要受太平洋板块和菲律宾板块与欧亚板块相互作用的控制。近年来,地球系统多圈层构造观的提出为深入理解东亚洋陆汇聚系统各圈层之间的相互作用提供了新的思维。本文以地球系统多圈层构造观为指导,依托1:100万海洋区域地质调查实际资料与成果,在东亚大陆边缘多圈层动力系统的框架内,对中国海域及邻区的地质构造进行了总结,初步形成了以“一个边缘、两次消减、三期伸展、分层控制”为核心的“东亚洋陆汇聚边缘多圈层相互作用”理论模式,并进一步提出新的构造单元划分方案。本文首次将大洋板块与大陆边缘稳定地块之间的区域,划分为“东亚大陆边缘汇聚带”这一独立的一级构造单元,按照构造演化的差异,以台湾岛界大致可以分为北部的日本—琉球段和南部的菲律宾段“。东亚大陆边缘汇聚带”以全新视角诠释了中—新生代以来在西太平洋俯冲汇聚系统下,东亚大陆发生的多期次地质构造事件的深部板块动力学过程,特别是在菲律宾海板块俯冲背景下,形成了中国海域东部带状变化、南部环状变化的地貌特征。海域地貌格局进一步控制了东部海域“大江大河—大三角洲—陆源碎屑—条带状”和南部海域“短源河流-高角度陆坡-混合物源-环状分布”的沉积分异模式。

Abstract:
The Mesozoic-Cenozoic tectonic activity in eastern China was mainly controlled by the interaction of the Pacific plate and the Philippine plate with the Eurasian plate. In recent years, the concept of multisphere tectonics of earth system has provided a new perspective for understanding the interaction between various layers of the East Asian convergence system. Based on the 1:1 million marine regional geological survey, this paper comprehensively summarizes the geological structure of China's sea areas and their adjacent areas, initially forming the “multisphere interactions in East Asia ocean-continent convergence zone” with the core of “one margin, two-stage subduction, three-stage extension, and hierarchical control”. In addition, a new first-order tectonic unit division scheme was first proposed in the region between the oceanic plate and the continental margin, referred to as “East Asia continental margin convergence zone”. According to the differences of tectonic evolution, this tectonic unit could be roughly divided into the northern Japan-Ryukyu section and the southern Philippine section based on Taiwan Island. “East Asia continental margin convergence zone” has provided a powerful explanation for the geodynamic process of multiple geotectonic events in East Asia under the West Pacific subduction and Philippine Sea plate subduction system since the Meso-Cenozoic. It formed geomorphic features in China's sea areas which show zonal variation in East China's sea areas and cyclic variation in South China's sea areas. The geomorphic framework further caused the sedimentary differentiation model of “Great River-Great Delta-Terrigenous-Banded” and “Short source river-High angle slope-Multisource-Annular” in East and South China's sea areas, respectively.
