Recently it has been proposed that the term Kibaran should be given a much more restricted meaning, referring only to a tectono-magmatic event around 1375 Ma in which the Karagwe-Ankolean belt was formed in a region extending from the north of Lake Tanganyika to the south of Uganda, and that the term Kibaran belt should be confined to the belt around the Kibara mountains in the southeast of the Democratic Republic of the Congo.
