Sedimentary phosphorites as geochemical sponges: trace element scavenging, the chemical evolution of seawater and an innovative method for dating sediments

点击翻译按钮获取中文摘要

Ancient sedimentary phosphorite is the major source of commercial phosphate in Australia and East Asia. This project will lead to economic and environmental benefits to Australia by providing the minerals industry with the tools to target purer phosphate, thus improving resource estimations and minimising the environmental impact of trace metal burdened fertiliser. The study will enhance our understanding of the nature and timing of key moments in Earth history and could serve as a launchpad for future studies on the use of phosphate for environmental remediation. We hope to provide exciting opportunities for Australian postgraduates through cutting edge research in partnership with both homespun and international academic collaborators.
