摘　　要：本文根据岩性、沉积结构、胶结物成分、胶结类型和产状等特征区分海滨砂丘岩与海滩岩,从而把福建莆田笏石半岛—湄洲岛地区的海滨砂丘岩从以往所称的海滩岩中划分出来。为了便于鉴别,文中对海滨砂丘岩、潮上带海滩岩和潮间带海滩岩的特征作了对比。In the survey of beach rock in the Hushi Peninsula and Meizhou Island, Fujian, we discovered that some of them were coastal dune rock instead of beach rock. Beach rock and coastal dune rock are totally different in origin and, they must be strictly differentiated based on the following characteristics: content and completeness of bioclastic, grain size, content type and degree of cementation, bedding structure and relief of bottom boundary. According to these characteristic coastal dune rock, supratidal and intertidal beach rocks can be easily distingushed. We believe that the so-called beach rocks distributing on higher and middle part of the coast of putian, are coastal dune rock instead. They may not be taken as indicators of sea level change and crustal movements, The supratial and intertidal beach rocks formed in the different parts of the beach can not survive in the relative changes of sea level and crustal movement.
