现代实例和岩石记录的研究表明,微生物席是一个特别的微生物群落,这个特殊的微生物群落就像一个复杂的食物网一样,群落中的每一个组成成员紧密相互依赖,从而构成了地球上形成最早、延续时间最长的生态系。微生物席在沉积岩中留下了丰富而且复杂的记录,在碳酸盐岩中最为典型的产物就是叠层石,在碎屑岩中最具有代表性的产物就是“微生物诱发的沉积构造(M ISS)”。对这些特殊沉积记录的长期研究和探索,产生了沉积学在地球生物框架下的一个年轻分支——“微生物席沉积学”;这个以微生物席为研究对象的年轻的沉积学分支,在研究地球早期生命演变、探索生物圈对水圈和大气圈的长时间影响,具有重要意义。若干的新概念和新思维,赋予这个年轻的沉积学分支强大的生命力,同时也代表了沉积学在近年来的一个重要进展之一。 Studies of modern examples and rock records show that the microbial mat is a special microbial community that acts like a complex food web and that each member of the community is closely interdependent and thus forms the earliest formation on Earth , The longest continuation of the ecosystem. The microbial mat leaves rich and complicated records in sedimentary rocks. The most typical product in carbonate rocks is stratigraphic rocks. The most representative product in clastic rocks is the microbial sediment structure (M ISS) “. The long-term research and exploration of these special sedimentary records have resulted in a young branch of sedimentology under the framework of the Earth’s biology - the ”sedimentology of microbial beds". This young branch of sedimentology, Studying the evolution of the early life of the earth and exploring the long-term effects of the biosphere on the hydrosphere and the atmosphere are of great significance. A number of new concepts and new ideas have given this young branch of sediment a strong vitality, but also represents one of the important advances in sedimentology in recent years.
