Knowledge about how the Earth's crust is stretched and eventually broken apart to form new ocean basins is fundamental to understanding the evolution of the continents, their resources and the surface environment of our planet. This project combines new methods of analysing the temperature history of rocks to trace their progress towards the surface with direct measurements of the rate of surface erosion following extensional movements. This integrated approach will be used to examine some of the best-characterised examples of continental extension in Arizona, Mexico and Africa to cast new light on the development of older extensional environments in Australia.

了解地壳如何拉伸并最终分裂形成新的海洋盆地，对于了解大陆及其资源和地球表面环境的演化至关重要。 该项目结合了分析岩石温度历史的新方法，以追踪其向表面的进展，并直接测量拉伸运动后的表面侵蚀率。 这种综合方法将用于研究亚利桑那州、墨西哥和非洲一些最具特征的大陆扩张例子，为澳大利亚较早的扩张环境的发展提供新的线索。
