Ancient sedimentary rocks record evidence of major climate change and variations in the composition of the atmosphere. By applying novel isotopic and geochemical techniques, this project aims to document when and how the Earths atmosphere and climate changed prior to the evolution of complex lifeforms. Curiously, such dramatic climate changes have controlled both the rate of evoutionary process and the formation of world class mineral deposits.

古代沉积岩记录了重大气候变化和大气成分变化的证据。通过应用新的同位素和地球化学技术，该项目旨在记录复杂生命形式进化之前地球大气和气候的变化时间和方式。奇怪的是，如此剧烈的气候变化控制了演化过程的速度和世界级矿床的形成。
