Accretionary mountain belts constitute major portions of the Earth's continental crust including the Yilgarn in Western Australia and the area east of Broken Hill constituting a third of the Australian land mass. Understanding the origin of the Permo-Triassic (300-230 Ma) mountain range that lay along the margin of Gondwana from Eastern Australia to South America will provide a new insight into our environment and stimulate international interest through collaboration amongst researchers around the world. Accretionary orogens are of economic importance as they host the Earth's major orogenic gold deposits and our work has potential to provide a new framework for linking mineralization and deformation events within these important settings.

吸积山带构成了地球大陆地壳的主要部分，包括西澳大利亚州的伊尔加恩和布罗肯山以东的地区，构成了澳大利亚陆地的三分之一。了解二叠纪-三叠纪(300-230 Ma)山脉的起源将提供对我们环境的新见解，并通过世界各地的研究人员之间的合作激发国际兴趣。增生造山带具有重要的经济意义，因为它们承载着地球上主要的造山带金矿，我们的工作有可能提供一个新的框架，将这些重要背景下的矿化和变形事件联系起来。
