New insight into iron-dependent subsurface biospheres on Earth and other planetary systems

Iron is one of the major rock-forming elements on planets such as Earth. When rocks are from deep within the crust are tectonically exposed to water, large disequilibria between Fe (II) and the fluids results in electron flow that can power microbial life. I will discuss new insights into Fe-dependent microbial life in the Earth's subsurface, and the potential importance of Fe geochemistry in sustaining life activity in rocky planetary systems where water might be present.
