摘　　要：通过岔路口地区向阳峰一带地质填图和实测地层剖面,在原划中泥盆统落石沟组中采到了大量腕足、珊瑚类化石,经鉴定其形成时代为早石炭世中期。该套地层与西邻地区区域地层对比,厘定为早石炭世帕斯群。该生物化石的取得,为该套地层时代划分提供了依据,为进一步分析研究甜水海微陆块地层层序格架及地层演化,提供了新资料。In geological survey and measuring stratigraphic profiles conducted in Xiangyangfeng area of Chalukou district, a large number of brachiopods and coral fossils have been discovered in the former attributed to the Laoshigou Formation of Middle Devonian. It is identified that the age of its formation is the middle of Early Carboniferous. The strata are correlated to the regional strata in the western adjacent area and are identified as the Early Carboniferous Pass Group. The acquisition of those fossils provides a basis for the division of stratigraphic age, and provides new data for the further analysis of the stratigraphic sequence framework and stratigraphic evolution of the Tianshuihai micro-continental block.
