[1] Recently, it has been proposed that the term should be used in a much narrower sense for an event around 1375 Ma and a region in the southeast of the Democratic Republic of the Congo (DRC).
Regions that contain relics of Kibaran age include the Kibara Mountains of the eastern DRC and Namaqua-Natal belt in southern Africa.
The orogeny in northwest Nigeria was a major tectonic and thermal event that apparently was floored by an older continental basin.
Local names for the segments, from north to south, are the Karagwe-Ankolean, Burundian, Kibarides, Irumides, Choma-Kalomo, Ngamiland, Namaqua-Natal and Lurio belts.
Apparently it is not orogenic but is an intracratonic large igneous province formed in the boundary between the Tanzania craton to the east and the Eburnean-aged mobile belt to the west.
