| 摘 要： | 通过对哈拉奇地区泥盆系岩石学特征、层序地层格架、岩石地球化学特征和沉积构造的研究，对研究区泥盆纪地层进行了层序地层划分和沉积环境的恢复。研究区泥盆系划分为4个三级层序，沉积物源区主要为被动大陆边缘的再旋回造山带物源区，研究区泥盆系为无障壁滨浅海沉积环境。构造运动和海平面升降系该区泥盆系三级层序及其内部体系域形成的主要控制因素。

| Abstract: | Through the study of petrological characteristics, sequence stratigraphy, geochemistry, sedimentary structures of Devonian period, the authors divided the sequence stratigraphy and restored sedimentary environment of Devonian. The Devonian strata can be divided into four third sequences. The source area was mainly provenance of recycled orogenic belt on passive epicontinental margin. The sedimentary environment was a barrier-free littoral-neritic environment in Devonian. The major factors that controlled the formation of these three tertiary sequences were structural movement and sea level fluctuation in Devonian. |
