This project aims to investigate how solid Earth processes contributed to ‘Snowball Earth’ events around 700 million years ago and to the explosion of complex life 540 million years ago, which will shed light on our origin as a species. The approach consists of merging cutting-edge models of the plate-mantle system with the global rock record. The intended outcome is to understand relationships between mantle convection, the behaviour of the magnetic field, global sea levels, continental-scale topography, and the composition of the ocean and atmosphere. Expected significant benefits include building capacity in Earth Sciences and the development of new models that can be used to explore the mineral endowment of the Australian crust.

该项目旨在调查大约7亿年前的扎实地球过程对“滚雪球”事件的贡献，并在5.4亿年前的复杂生活爆炸中爆炸，这将阐明我们作为一种物种的起源。该方法包括将板球系统的尖端模型与全球岩石记录合并。预期的结果是了解地幔转换，磁场的行为，全球海平面，大陆规模的形态以及海洋和大气组成之间的关系。预期的重大好处包括地球科学的建筑能力以及可用于探索澳大利亚地壳矿物质的新模型的开发。
