| 摘 要： | 本文根据对福建省不同地区的地质特征进行详细的研究对比，划分出闽西北、闽西南、闽东和闽东南四个性质不同的地体，并研究了各地体的之间碰撞拼贴的历史，指出它们主要经历了三个阶段：1、晚元古代，闽西南地体和闽西北地体沿南平-宁化一线发生碰撞拼贴作用，同时伴随海底和陆上火山喷发活动；2、三叠纪，闽东地体沿政和-大埔一线和闽西南、闽西北地体发生碰撞拼贴作用，闽东南地体也随之拼贴在闽东地体之上；3、白垩纪，闽东南地体沿平潭一东山断裂带发生左行走滑运动。

| Abstract: | Based on abundant geological data, this paper divides geologically Fujian province into four distinct terranes, namely, Northwest Fujian terrane, Southwest Fujian terrane, East Fujian terrane and Southeast Fujian terrane,and correlates their geological features in detail respectively. Through the study on collision-amalgamation history of each terrrane, it can be concluded that they mainly underwent three stages：（ 1 ）in Late Proterozoic ,the Southwest Fujian terrane and Northwest Fujian terrane collided and amalgamated along the Nanping-Ninghua fracture zone, being accompanied by submarine and continental volcanic eruptions; （2）in Triassic ,the East Fujian terrane collided and amalgamated with the Southwest Fujian terrane and Northwest Fujian termne along the Zhenghe-Dapu fracture belt,and the Southeast Fujian terrane amalgamated simultaneously with the East Fujian ten：ane; （3） in Cretaceous, the Southwest Fujian terrane underwent a left-lateral strike slip along the Pingtan-Dongshan fracture zone. |
