Abstract

Microbial carbonate rocks are classified into stromatolite, dendrolites, thrombolite, and leiolite based on their mesoscale features. Additionally, there are also oncolite and laminite. Based on field exploration sampling and combined with indoor thin section analysis, dendrolites was observed in the Changshan Formation of the Cambrian period in the Zhi Dongyu section of Shandong. It has a thickness of approximately 75 meters and, together with blocky oolitic grainstone, forms the upper part of a third-order depositional sequence that constitutes a late highstand systems tract (LHST). Macroscopically, obvious branching clots can be observed in dendrolites, while microscopically, the development of various calcifying cyanobacteria such as Girvanella, Epiphyton and Hedstroemla can be seen. In terms of Chronostratigraphy, microbial reefs dominated by dendrolites are relatively rare in the Furong Formation's Changshan Formation. Therefore, this study provides an important example for the subsequent research on dendrolites in the Changshan Formation. Additionally, the discovery of Epiphyton in the Changshan Formation contradicts the claim that they were extinct during the Late Ordovician mass extinction. What is more, the abundance of Hedstroemla also raises doubts about the previous belief that Epiphyton dominate the formation of dendrolites clots, emphasizing the importance of Hedstroemla in the formation of dendrolites clots.
