|This project combines interpretation of satellite images, detailed structural field mapping, kinematic
analysis of faults, numerical modelling of fault patterns and fault growth, and dating of clay-rich fault
gouge to answer the following questions: (1) Do fault kinematics change during rifting and if, are changes in
fault kinematics important for extreme rift-flank uplift? (2) What is the age of different fault generations?
(3) How can extreme uplift of a few rift blocks take place? Faults will be mapped using satellite images and
areal photographs and key faults will be identified and structurally mapped in detail. It is important to see
whether or not various generations of faults exist and, if so, whether these different generations have
different kinematics. If there are changes in fault kinematics (strike-, oblique vs dip-slip) in time, then
the questions arises as to how these changes are related to the uplift of the Rwenzori Mountains. Dating of
fault gouges will date possible changes in rift kinematics and age of faulting can be compared with data from
low-temperature chronology to test whether or not kinematic changes coincided with uplift pulses. GPS
measurements will constrain large-scale plate motions and can be used to define external boundary conditions.
Fault patterns that develop in the numerical model as a function of external boundary conditions will be
compared with the natural examples in order to obtain a better understanding of the extreme uplift of the
