The project aims to reconstruct 250 million years of landscape evolution in response to rifting and break-up of the Gondwana supercontinent, using the innovative approach of combining regional thermochronology with global plate tectonic models. From these reconstructions, the time-integrated record of exhumation and erosion at the continental margins will be revealed at an unprecedented scale. The main expected outcome will be a deep time archive of the relationships between tectonic forcing, continental erosion and the global climate, which may assist predictions and debate on future climate change. The outcomes will also provide economic benefits as they will inform on the exhumation and preservation of (critical) mineral resources.

该项目旨在利用区域热年代学与全球板块构造模型相结合的创新方法，重建 2.5 亿年的地貌演化过程，以应对冈瓦纳超大陆的裂谷和分裂。通过这些重建，大陆边缘折返和侵蚀的时间整合记录将以前所未有的规模被揭示。主要预期成果将是构造强迫、大陆侵蚀和全球气候之间关系的深度时间档案，这可能有助于对未来气候变化的预测和辩论。研究结果还将带来经济效益，因为它们将为（关键）矿产资源的挖掘和保护提供信息。
