应用构造—岩性—事件法将五台山碰撞造山带划分为3个构造片体:弧前混杂岩带、古岛弧系和弧后混杂岩带。提出该造山带构造演化5个阶段:洋盆扩张阶段(>2600Ma);南部洋盆向微陆块下俯冲—微陆块转化为岛弧阶段(2600~2500Ma);弧前碰撞—弧后消减阶段(2550~2500Ma);陆—陆碰撞阶段(2550~2450Ma);伸展作用阶段(2500~2400Ma)。
Using the tectono-lithology-event method, the Wutaishan collision orogenic belt is divided into three tectonic slices: pre-arc melange belt, ancient island arc system and backarc melange belt. The tectonic evolution of the orogenic belt is proposed to be characterized by five stages of tectonic evolution: ocean basin expansion (> 2600Ma); subduction of micro-continental blocks in the southern ocean basin-micro-continental blocks to island arc (2600-2500Ma) Stage (2550 ~ 2500Ma); continental-continental collision stage (2550 ~ 2450Ma); stretching stage (2500 ~ 2400Ma).
