This project will use a range of innovative geochemical techniques to constrain the timing and extent to which the continents were emergent (above sea-level) throughout Earth’s history and its impact on climatic evolution. Continental emergence was pivotal to the development of our habitable planet, as it controlled the influx of bioessential elements, like phosphorus, to the oceans. Expected outcomes include a detailed record of changes in ocean chemistry, and a time integrated model for the emergence of continents on the early Earth. Documenting the impact of changes in the solid Earth on evolution is not only of interest to society in general, but also contributes to understanding the formation of Australia’s vast iron ore deposits.

该项目将使用一系列创新的地球化学技术来限制地球历史上大陆出现（海平面以上）的时间和程度及其对气候演变的影响。大陆的出现对我们这个宜居星球的发展至关重要，因为它控制了生物必需元素（如磷）向海洋的流入。预期的结果包括海洋化学变化的详细记录，以及早期地球大陆出现的时间综合模型。记录固体地球的变化对进化的影响不仅引起了社会的普遍兴趣，而且有助于了解澳大利亚巨大铁矿床的形成。
