The Ruwenzori mountains lie between Albert and Edward lakes on the Uganda-Belgian Congo boundary. In the northern part, the rocks are an alternating succession of biotite gneiss, biotite granite, and plagioclase amphibolite of migmatitic origin. Rift faults striking north-northeast are rejuvenations of Precambrian fault lines. Faulting in other directions is present, together with jointing, and probably took place in Precambrian time as a result of compression.
