本文讨论福建及毗邻大陆地壳,中、新生代时期活动大陆边缘,几个阶段的演化特点。印支 阶段,断块强烈,地壳分异明显,各种类型的盆地发育;燕山阶段,地壳的急剧隆和裂陷,大规 模的断裂、火山、岩浆活动,构成东南沿海的复杂构造带,喜山阶段,陆缘的弧后扩张和岛弧的 造山作用。整个过程受着古太平洋板块对亚州板块多阶段的俯冲控制。
This article discusses the evolutionary features of the continental margin, several stages of activities in the crust, adjacent to the continent and during the Meso-Cenozoic period. During the Indosinian phase, strong block faulting and obvious crustal differentiation have resulted in the development of various types of basins; the Yanshanian stage, the rapid crustal and rift of the crust, large-scale faults, volcanic and magmatic activities, the complex structural belt that forms the southeast coast, Mountain stage, the edge of the arc after the expansion and island arc orogeny. The whole process is controlled by the multi-stage subduction of the Paleo-Pacific plate to the Asian plate.
