Characteristics of Terrestrial Microbial Mat-Example from Liujiagou Formation of Yiyang, Henan

In recent years, the research on Microbially Induced Sedimentary Structures (MISS) and their biogeological processes has developed rapidly, and has attracted the attention of many scholars. These studies are mainly concentrated in the marine Precambrian. There are few studies on the structure of terrestrial microbial mats. Therefore, this paper takes the terrestrial Liujiagou Formation as the research object, and describes and studies the mat growth structure (nodular protrusions, Kenyan ripples, reticular growth ridges), mat destruction (mainly various forms of dehydration cracks, mainly including: spindle, polygonal mesh, curved, dendritic dehydration cracks), mat decay (gas escape structure and sand volcano) in the study area in detail.
