| 摘 要： | 伊犁盆地是在天山造山带所夹持的微地块上发展演化而成的山间叠合盆地，其现今垂向结构为自下而上由中、新元古代变质基底、石炭纪裂谷火山岩系变形基底和二叠纪以来的盆地沉积岩系组成的３ 层结构，南北向剖面形态总体为两侧造山带相对向盆地逆冲的对冲构造几何学样式，伊犁盆地内则呈现为二山三盆的复杂次级山 盆构造组合。伊犁盆地的形成演化与天山造山带，尤其与其南北两侧相邻的不同性质造山带密切相关。伊犁地块和盆地的形成演化可概括为４ 个大的构造阶段和４ 个成盆期。现今的伊犁盆地正是不同成盆期的原型盆地复合叠置的综合产物。石炭－ 二叠纪和侏罗纪是伊犁山 盆构造系统的主造山成盆期。

| Abstract: | Yili Basin is a composite intermontane basin formed on micro massif in Tianshan orogen.Vertical structure of Yili Basin from bottom to top could be divided into three structural layers including Meso Neoproterozoic metamorphic basement,Carboniferous deformation basement of igneous rocks in the setting of rift, sedimentary series since Permian. The geometric style of SN directed profile of the basin is duplex thrusts from two sided orogens toward the basin.Yili Basin includes two faulted uplifts and three sub basins now.The formation and evolution of the basin are related to Tianshan orogen, especially to two sided neighbouring orogens with different features.The formation and evolution of the basin could be summarized into four structural stages and four basin forming stages in which their protoformed basins are interposed into Yili Basin.Carboniferous Permian and Jurassic are major basin forming and orogenic stages. |
