摘　　要：为进一步研究哈拉奇地区古生代沉积地质,根据研究区的岩性、岩相建造、古生物化石、沉积演化、沉积构造等基本数据,采用野外观察与室内研究相结合的方法,对古生代的沉积环境进行了分析。结果表明,该区古生代岩性组合依次为灰岩-砂岩-灰岩-白云质灰岩,反映了海退-海进-海退的沉积序列。This paper analyzed the sedimentary environment of Paleozoic strata in the Halaqi region for further re- searches on the sedimentary geology. Field observation was combined wiih in-house studies in the aspects of li- thology, lithofacies construction, paleontologic fossil, sedimentary evolution and sedimentary structure. The litho- logical association is limestone-sandstone-limestone-dolomitic limestone in Paleozoic. It is Suggested that the sedimentary sequence is regression-transgression-regression.
