摘　　要：介绍了国内外学者在灰岩分类方面的研究成果,指出,1962年Folk的分类和Dunham的分类实用性很强,在灰岩分类史上具有里程碑的意义。而1971年Embry对Dunham分类体系的修订与1992年Wright对灰岩分类的进一步完善,以及2000年Riding对微生物岩的划分是灰岩分类的3次重大进展,使得灰岩分类逐步科学、合理和完善。鉴于生物(尤其是微生物)作用在灰岩成因中的重要性和复杂性,结合Riding的分类——将微生物岩划分为叠层石、凝块石、树形石和均一石以及近年来生物作用类灰岩的研究进展,对灰岩分类体系作了进一步补充和完善。The results of limestone classification gained by scholars at home and abroad are introduced. It is pointed out that Folk＇s division （1962） and Dunham＇s division are good in practicability, hence being milestone＇s significant in the history of limestone classification. And EmbryOs modification （1971） and Wright＇s further revision （1992） as well as Riding＇s division of microbolite （2000） can be regarded as three major progresses for it. It is ＂two milestones＂ and ＂three progresses＂ that allow the limestone classification to be more scientific, more reasonable and more perfect. In view of the importance and complexity of biotic （esp. microbial） processes in formation of limestone, together with Riding＇s division of microbolite into stromatolite, thrombolite, dendrolite and leiolite as well as recent-year studied progress, this paper suggests new complements and perfections for limestone classification.
