COLLABORATIVE RESEARCH: Uplift History of the Red Sea Margin in Egypt and Sudan from Fission Track Analysis and Its Implications for Rift Propagation

在大陆裂陷开始时，大陆地壳的裂谷边缘可能与裂谷内部沉降和伸展的主阶段同步发生隆升。先前来自苏伊斯湾的数据表明，这种关系是成立的，根据基底裂变轨迹确定的隆升起始时间，是红海裂谷快速伸展开始时间的一个很好的代表。该项目将沿着埃及和苏丹的红海边缘进行裂变轨迹取样。所得到的数据将用于确定裂陷是沿着整个裂谷同步进行还是从南部传播。这些数据还将与地层数据结合使用，以更好地限制苏伊斯湾抬升和侵蚀的速度和幅度。研究结果有望提高对大陆裂陷早期裂谷侧翼行为的认识。

During the onset of continental rifting, the rifted edges of the continental crust may undergo uplift synchronously with the start of the main phase of subsidence and extension within the rift itself. Previous data from the Gulf of Suez indicate that this relationship holds, and the initiation of uplift, as dated by basement fission tracks, makes an excellent proxy for timing the onset of rapid extension in the Red Sea Rift. This project will conduct fission track sampling along the Red Sea margins in Egypt and Sudan. Resulting data will be used to determine whether rifting proceeded synchronously along the entire rift or propagated from the south. These data will also be used in conjunction with stratigraphic data to better constrain the rates and magnitude of uplift and erosion at the Gulf of Suez. Results are expected to improve understanding of the behavior of rift flanks during early stages of continental rifting.
