Thermal histroy, denudation, uplift, and log-term landscape evolution of the Rwenzori Montains, Uganda

该项目的目的是量化乌干达鲁文佐里山脉的热、隆起和剥蚀历史。鲁文佐里山脉是东非裂谷中裂谷翼隆起的关键地区。鲁文佐里山脉高度约5000米，影响区域大气环流，从而对中非的气候产生重大影响。该项目将联合收割机结合磷灰石裂变径迹和磷灰石（U-Th）/He热年代学的结果，建立该地区的热、隆升和剥蚀历史。在某种程度上，这一目标将通过2-D和3-D热动力学建模来实现，通过使用/定制现有的计算机代码来整合表面过程。测试模型的解决方案（即预测）获得的多维参数空间（热参数，隆起，侵蚀速率，构造边界/相对运动）对真实的热年代学数据集，最可能的参数值的组合可以被约束。RJFLE项目最相关的可交付成果将是（i）快速隆升开始的时间和（ii）隆升和剥蚀速率的时空演变。

The aim of the project is to quantify the thermal, uplift and denudation history of the Rwenzori Mountains, Uganda. The Rwenzori Mountains are a key area for rift-flank uplift in the East African Rift. Because of their significant height of about 5000 m the Rwenzori Mountains influence regional atmospheric circulation and thereby have a significant impact on the climate in central Africa. The project will combine the results of apatite fission-track and apatite (U-Th)/He thermochronology to establish the thermal, uplift and denudation history of this region. In part, this aim will be achieved by 2-D and 3-D thermokinematic modelling, integrating surface processes by using/customizing existing computer codes. Testing model solutions (i.e. predictions) obtained for the multidimensional parameter space (thermal parameters, uplift-, erosion rate, tectonic boundaries/ relative movements) against the real thermochronolgical data set, the most likely combinations of parameter values can be constrained. Most relevant deliverables for the RJFLE-project will be the (i) timing of onset of rapid uplift and (ii) spatial and temporal evolution of uplift and denudation rates.
