| 摘 要： | 简要论述了西秦岭造山带显生宙以来的构造演化和格局,讨论了西秦岭造山带的性质.西秦岭造山带自800Ma左右以来,经历了超大陆裂解、洋陆演化、碰撞造山、板内伸展和陆内叠覆造山后才形成现今的西秦岭造山带.在不同的构造演化阶段,西秦岭有着完全不同的构造体制和格局.在洋陆演化阶段属板块构造体制,以多陆块洋为特征的洋陆格局;在板内伸展阶段属板内裂谷和裂陷盆地体制,以板内伸展盆地体系为特征的海陆格局;在陆内叠覆造山阶段属陆内盆山体制和陆内盆山格局.西秦岭造山带是一个"碰撞—陆内型"复合造山带.

| Abstract: | In this paper tectonic evolution,framework and nature of the West Qinling Orogenic Belt after Phanerozoic Ph.have been discussed.Since about 800 MaP.B.,the West Qinling Orogenic Belt underwent break-up of supercontinent,evolution of ocean and continent,collisional orogeny,within-plate stretching and incontinental overprinted orogeny,and presentday West Qinling Orogenic Belt has been eventually completed.During diffirent tectonic evolutional stages,the West Qinling Orogenic Belt has various tectonic style and framewo rk.In the evolution stage of ocean and continent,its tectonic style belongs top late tec-tonics,and it is charecterized by framework of ocean and continent.In with in-plate stretching stage,its tec-tonic style belongs to a with in-plate rift and fault-subsiding basin,and it is charecterized by a framework of sea and continent. |
