摘　　要：在综述皱饰构造成因研究历程和国内外最新研究成果的基础上,总结评述了4种有代表性的皱饰构造形成模式,其核心问题是在皱饰构造的形成过程中微生物席和物理作用的参与方式,以及受造席者、透光性、水动力条件、基底类型和生物扰动五大因素的影响程度。在对皱饰构造和现代微生物席对比研究的基础上,发现皱饰构造与微生物席的分布在很大程度上具有一致性,所以通过对现代微生物席的生长发育环境进行综合研究,推测了有利于皱饰构造发育的古环境。皱饰构造一般发育于潮间坪和滨外过渡带,并且在显生宙一般与生物扰动作用具有不相容性。皱饰构造是发育最普遍、受关注最广泛的保存在硅质碎屑岩中的微生物诱导形成的原生沉积构造,所以理清皱饰构造的成因模式及古地理分布,有利于碎屑岩微生物席学的发展,可以为理解硅质碎屑岩中的特殊沉积构造提供重要线索。On the basis of the research course analysis and the latest investigation on wrinkle structure,four dominating origin models are outlined.The core issue is what kind of role played by microbial mat and physical process,and the influence of mat-builder,light penetration,hydrodynamic energy conditions,substrate,and bioturbation in the formation of wrinkle structure.The comprehensive research on wrinkle structure and modern microbial mat show that the distribution of wrinkle structure and microbial mat is consistent to a great extent.So the paleoenvironment of wrinkle structure is outlined through the study on modern microbial mat environment.Wrinkle structure generally develops in intertidal flat and offshore transition,and does not associated with massive bioturbation in Phanerozoic.Wrinkle structure is most common microbial induced sedimentary structure preserved within the siliciclastic rock record.Thus understanding the genetic origin and paleoenvironment distribution of wrinkle structure promote the development of the microbial mat sedimentology in clastic rocks.
