摘　　要：通过对乌拉斯泰一带的沉积相、侵入岩及火山岩的构造环境分析,结合以往成果,认为乌拉斯泰一带经历了古准噶尔洋的形成和发展、乌拉斯泰泥盆纪裂陷槽的形成和发展、晚古北天山有限洋的形成和发展以及陆内造山及隆升4个阶段,剖析了乌拉斯泰泥盆纪裂陷槽的确立,修正了西天山造山带的构造区划及演化史。Through the analysis oftectonic setting of sedimentary facies,intrusive rock and volcanic rock in Wulasitai area,which passes through four stages including formation and development of ancient Junggar Ocean,formation and development of aulacogen of Devonian,formation and development of late ancient North Tianshan ocean and intra-continent orogeny uplift.The authors analyze establishment of aulacogen of Devonian,fix the western Tianshan orogen divisions and its history.
