摘　　要：为了解皖北新元古代沉积环境,在详细的野外地层学工作基础上,结合室内岩石学分析,识别出几种特殊的岩石类型。通过岩相学、沉积学的研究,综合利用野外沉积构造,分析了宿州地区新元古代的沉积环境。研究表明,宿州地区新元古代整体为一套碳酸盐岩建造,以陆表海沉积为主,海平面升降频繁,共有四次沉积旋回,并均伴有地震活动。For the sedimentary environment of Neoproterozoic in Suzhou district,detailed stratigraphy study has been completed outside,petrology analysis finished indoor,and several types of rock are indentified.The Neoproterozoic environment in Suzhou district has been postulated by the study on petrography,sedimentology and sedimentary structure field.The results imply that the Neoproterozoic environment in Suzhou district is continental sea,constructed by carbonatite,the sea-level rises and falls frequently with four sedimentary cycles,with seismic activities.
