| 摘 要： | 北山造山带经历多期次、多阶段的板块裂解-俯冲-碰撞-拼合的复杂地质演化历程,具多旋回复合造山的特色。通过对造山带构造单元的建立、古板块重建、原型盆地恢复、造山带结构、构造特征及造山机制和模式的研究,确定北山造山带类型为陆-增生弧碰撞造山带。

| Abstract: | Beishan orogenic belt passed complex geological evolution by multistage plate divergence subduction collision fitting, with the characteristics of ploycycle multiple orogeny Through studying about tectonic units established, old plates rebuilded, original basins restored, texture and structure of orogenic belt, mechanism and model of orogeny, it is definded that the type of Beishan orogenic belt is continent accretion arc collosion orogenic belt |
