Engineering planetary habitability: Earth’s first billion years. This project aims to establish the critical physical-chemical factors in the early surface environment and tectonic regime that supported early life and continuing habitability. Life was established on Earth within the first billion years of its 4.56-billion-year history. This project’s integrated geological and geochemical study will investigate this period’s rare sedimentary and volcanic record, including the oldest fossiliferous ....Engineering planetary habitability: Earth’s first billion years. This project aims to establish the critical physical-chemical factors in the early surface environment and tectonic regime that supported early life and continuing habitability. Life was established on Earth within the first billion years of its 4.56-billion-year history. This project’s integrated geological and geochemical study will investigate this period’s rare sedimentary and volcanic record, including the oldest fossiliferous sequences discovered recently, to show how the early Earth’s chemistry supported life and evolution. The project expects to enhance understanding of why life prospers on some habitable zone planets but not on others.Read moreRead less
