The interfaces between mineral grains are critical in determining rock properties and behaviour, yet we know little about them. This project uses emerging nano-technologies to establish the structure, chemistry and energy characteristics of interfaces in rocks from Earth’s mantle that control fundamental Earth processes such as plate tectonics and melting. The expected outcomes include a new understanding on one of the fundamental controls on rock properties and an enhanced ability to predict and model rock behaviour. The project provides research training in innovative research methodologies, will strengthen Australia’s leadership in nano-geoscience and will provide new methodologies for advanced rock characterisation.

矿物晶粒之间的界面对于确定岩石性质和行为至关重要，但我们对它们一无所知。该项目使用新兴的纳米技术来建立地球地幔中岩石中界面的结构，化学和能量特征，这些界面控制着地球基本过程，例如板块构造和熔化。预期的结果包括对岩石性能的基本控制之一的新理解以及预测和建模岩石行为的能力增强。该项目提供了创新研究方法的研究培训，将加强澳大利亚在纳米角度的领导，并将为先进的岩石表征提供新的方法。
