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.

该项目旨在在早期的表面环境和构造制度中建立关键的物理化学因素，从而支持早期生活和持续的居住能力。生命是在其45.6亿年历史的前十亿年内在地球上建立的。该项目的综合地质和地球化学研究将研究该时期的罕见沉积和火山记录，包括最近发现的最古老的化石序列，以展示早期地球的化学如何支持生命和进化。该项目希望增强对为什么生命为何在某些可居住区行星上生存而不是在其他行星上生存的理解。
