摘    要:通过研究沉积物的揭片以及粒度实验,分析了江苏中部海岸辐射沙洲区高潮滩上沉积物柱状样的原生沉积构造和沉积物的垂向粒度特征,并以此来解释辐射沙洲高潮滩的沉积环境,并发现砂/泥薄互层理既有风暴潮的成因,也有大、小潮周期性变化的成因。

关 键 词:辐射沙洲  沉积构造  砂/泥薄互层理  粒度特征  高潮滩沉积物  沉积动力学

Abstract:A dilling hole is obtained from the upper tidal flat of Radiation Sand Ridges in Jiangsu province. Based on its depositional features and granularity of the sediments, the author analyses the environment of sedimentation preliminarily and finds that the tide-flat laminae is the result either of the spring-neap tidal cycles or of the intercourse of storm and calm weathers.
Keywords:Radiation Sand Ridges  depositional features  tide-flat laminae  granularity
