The deep-sea hydrothermal system contains abundant hydrothermal precipitates and harbors a unique chemosynthetic-based ecosystem. Microbes can play roles on the mineralization of hydrothermal precipitates and seal-floor weathering of hydrothermal sulfide deposits. However, because the environmental conditions of hydrothermal system vary widely in space and time, and because microbial processes in hydrothermal fields are closely linked to chemical and geological processes, the role, mechanism and contribution of microbes to mineralization remain largely unexplored.

In this session, we will explore the role and mechanisms of microbial processes identified in the hydrothermal system and discuss how they interact with geological forces to shape the deep-sea environment. We invite researchers from diverse backgrounds to join us and share their insights and scientific results. Whether it's the discovery of novel microbial species that thrive in extreme conditions, insights into mineralization and biogeochemical cycles driven by functional microbes, or elucidation of the geological features that shape microbial habitats, all contributions are welcome. We aim to push the boundaries of our understanding of the complex coupling between geological, microbial and chemical processes in the deep-sea hydrothermal system.
