Review and prospect on the botryoidal structures from the Sinian Dengying Formation, Sichuan Basin, China

Fabric of carbonate rock is the important foundation and one of main research contents for study on carbonate sedimentology, and has always been the attention of the academic circles. Botryoidal structures from the Sinian Dengying Formation in the Sichuan Basin is a kind of special carbonate fabric, the fabric is named after the shape of a grape. In this paper, from four aspects of the research status, the definition of the botryoidal structures and the related terms, the construction characteristics of the botryoidal structures, the component of the botryoidal structures, geochemical characteristics and the genesis of the botryoidal structures are reviewed. It points out the current research issues of botryoidal structures from the Sinian Dengying Formation in the Sichuan Basin, and put forward that future research should focus on the accurate analysis of its internal construction, precipitation mechanism of the major components, and the construction mechanism of botryoidal structures.
