This project looks at the possible geodynamic driver for extreme uplift in the Rwenzori mountains, and adjacent rift flanks, reaching an altitude of about 5000 m a.s.l. within an extensional setting. Such extreme values cannot be explained at present, with any existing rift modelling scenario, which cuts off at about 2 km rift shoulder uplift. In the first three years of the project we will first address three different hypotheses for extreme uplift: 1) Uplift through significant volume of a vertical channel like melt intrusion, 2) Buoyancy through delamination of an old suture zone, 3) 3- D Modelling of transtension, with vorticity of the craton and secondary compression due to flip of rift shoulders.

该项目着眼于鲁文佐里山脉和邻近裂谷侧翼极端隆起的可能地球动力驱动因素，达到海拔约5000米。在一个延伸的环境中。这种极端值目前无法用任何现有的裂谷模拟方案来解释，该方案在约2公里的裂谷肩隆起处切断。在该项目的前三年，我们将首先解决三个不同的假设极端隆起：1）通过大量的垂直通道，如熔体侵入，浮力通过分层的老缝合带，3）3- D模型的transtension，涡的克拉通和二次压缩由于裂谷肩翻转。
