Funded Activity Summary

Toppling the Boring Billion: Biomarkers, orbital cycles and primordial life. This project aims to discover microbiological processes involved in ore formation in order to understand how zinc and lead minerals formed in the sediments of Australia’s ancient seas. The apparent ‘Boring Billion’ – the geological period 1800 to 800 million years ago – may have harboured seas of fluctuating colours. Fossil biomolecules, unearthed from 1.6 billion years old sediments, draw a picture of ancient seas oscillating between blooms of purple and green bacteria, with waters rapidly alternating between toxic and sulphidic and rich in dissolved iron. Based on these observations, the project aims to discover the dynamic nature of primordial ecosystems, investigate how ancient seas were controlled by the Earth’s orbit around the sun, and explore how microorganisms may have formed the world’s largest zinc deposits.
