摘　　要：对新疆东昆仑卡尔瓦西地区早古生代哈拉巴依沟组地层序列及其沉积特征进行了详细描述,介绍了该组地层的剖面特征、岩石组合,并进行了物源分析、粒度分析和年代探讨。工作区中的早古生代哈拉巴依沟组地层主要为一套中细粒碎屑岩为主的下粗上细非对称复杂地层序列。通过分析该套地层岩石及沉积学特征,指明了该区域哈拉巴依沟组地层的沉积特征及沉积相,暨判断其沉积相为大陆斜坡次深海相-深海相。The stratigraphic sequences and sedimentary features of the Early Paleozoic Halabayigou Formation in the Kaerwaxi area of Eastern Kunlun,Xinjiang,are described in detail.The profile features and rock assemblages of the strata are introduced,and the provenance analysis,grain size analysis and dating are discussed.The early Paleozoic Halabayigou Formation in the working area is mainly composed of a series of asymmetric complex strata mainly composed of finegrained clastic rocks.By analyzing the set of stratigraphic rocks and sedimentary characteristics,the sedimentary characteristics and sedimentary facies of the Halabayigou formation in this area are pointed out,and the sedimentary facies of this set of strata is continental deep-deep marine facies.
