Karst and pseudo-karst features in quartzite in Burundi. In Central Africa, underground karstic caves are to be found in precambrian carbonated series, but also in quartzite as in the case of Burundi. The arenisation process which took place during very wet periods of intense biological activity may explain the origin of these caves and of karstic landforms such as pavements and pinnacles.A côté d'un karst souterrain de type classique creusé dans les séries carbonatées d'Afrique centrale, des grottes et des phénomènes karstiques de surface existent également dans des séries quartzitiques comme c'est le cas au Burundi. L'arénisation de ces roches dans des structures fragilisées se produit dans un contexte très humide à forte activité biologi...
