The colonization of continents in late Paleozoic has changed the Earth system irreversibly. Evolution of vascular land plants and development of terrestrial ecosystem modify, e.g., the global C cycle, climate, and the landscape of continents, via various physical, chemical, and biological processes. It has been suggested that organic matter derived from land plant might have fueled complex biogeochemical cycles in terrestrial region, resulting in the formations of new deposits, such as coal and bauxites. Understanding how these new emerging biosedimentary rocks could linked to the vascular land plant would provide valuable insight into the Earth system evolution in this great transition. This session welcomes a wide range of topics related to biological and sedimentological processes in the eve of continent ecosystem in late Paleozoic. We welcome contributions of multidisciplinary researches, including but not limited to, 1) Evolution of geomorphology driven by early land plants, 2) Element cycles in continents associated with the ecosystem evolution, and 3) the relationship between biological depositions, element enrichments and ore formations, such as coal and bauxite.
