Modelling the extreme uplift in the Rwenzori Mountains: Insights from exogenic and endogenic numerical approaches

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.
