新疆巴尔鲁克山一带下-中泥盆统库鲁木迪组沉积相标志分析

摘要

The Lower-Middle Devonian Kulumudi group of the Barluk mountain area in Xinjiang West Junggar was widely considered to be the coastal neritic environment of deposition,and had less research for its sedimentary facies. From the point of rock association,sedimentary structures,fossils and particle size of sample analysis and so on,the paper based on the project of Laoyumin,Tasiti etc. seven geological survey progects in Xinjiang,further researches for Sedimen-tary facies signs of the Kulumudi group,and analysis which is composed of alluvial fan,fan delta and coastal-shallow sea facies.%新疆西准噶尔巴尔鲁克山一带下—中泥盆统库鲁木迪组被广泛认为是滨海-浅海沉积环境。本文依托新疆1∶5万老裕民、塔斯提等7幅区调项目，对库鲁木迪组沉积相标志进行研究，重点从岩石组合、沉积组构、生物化石及粒度样品分析等方面着手，认为其由冲积扇、扇三角洲及滨-浅海相组成。
