The 5th International Conference of Geobiology

The landing of plants has had a significant impact on biogeochemical cycles, particularly changing the transportation of elements related to terrestrial organic matter. Coastal marshes, as the first ecological niche occupied by mosses and ferns, exhibit numerous noteworthy features. Organic carbon from plants is buried and added to the sedimentary system of coastal zones, making sulfur reduction reactions and the fixation of other elements under reducing conditions. This study takes samples from the Haikou Formation of the Middle Devonian in South China as an example. It aims to reveal the influence of coastal vegetation on sedimentary systems. The perspectives include sedimentology and sulfur isotope geochemistry. Additionally, the study seeks to characterize the environment of water-rock-atmosphere interaction.
