This project will apply compound specific sulfur isotope analyses to sulfur-rich deposits from extreme environments including sulfidic black oozes (Peel-Harvey estuary); modern microbialites (for example, Shark Bay) and oils/source rocks (established and frontier oil fields). Sulfur isotopic data, integrated with other stable isotopic and molecular data, will greatly assist the study of sulfur biogeochemical cycles and mechanisms of organic sulfurisation at different diagenetic stages or geological ages. The project aims to address national concerns through measuring the respective impact of anthropogenic and natural changes on environments, helping to understand the evolution of life on Earth and contributing to efficient discovery of our natural petroleum systems.

该项目将对来自极端环境的富硫矿床进行复合特定硫同位素分析，包括硫化物黑色软泥（皮尔-哈维河口）；现代微生物岩（如鲨鱼湾）和油/烃源岩（已建立和前沿油田）。硫同位素数据与其他稳定同位素和分子数据相结合，将有助于研究不同成岩阶段或地质时代硫生物地球化学循环和有机硫化机制。该项目旨在通过测量人为和自然变化对环境的各自影响来解决国家关注的问题，帮助了解地球上生命的进化，并为有效发现我们的天然石油系统做出贡献。
