Sulfur Cycling in Toxic Oozes, Microbialites and Petroleum

该项目将对极端环境中的富硫矿床进行化合物特定硫同位素分析，包括硫化物黑色软泥（皮尔-哈维河口）;现代微生物岩（例如，Shark Bay）和石油/源岩（已开发和前沿油田）。硫同位素数据与其它稳定同位素和分子数据的结合，将大大有助于研究不同成岩阶段或地质时代的硫地球化学循环和有机硫化作用机制。该项目旨在通过测量人类和自然变化对环境的各自影响，帮助了解地球上生命的演变，并促进有效发现我们的天然石油系统，解决国家关切的问题。

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.
