Through the history of the Earth, surface environments had changed most dramatically on the early Earth, characterized by the formation of ocean, continents, and life. Large amounts of unclear points remained on the origin of life. Thus, this research area has large amounts of open questions to be achieved in the future. Geochemistry is one of the most powerful tool to answer the questions related to the origins of life. This special issue “Early Earth Chemistry” brings six review articles, in which the authors introduced unique aspects and recent progresses from the view of individual expertise. The contents cover the formation of oceans, formation of continents, impact events, prebiotic chemistry, and potential geological records of early life. We hope that you'll make the best from those overview contents and that this issue works to spread further novel research frameworks.
