Kibaran-Burundi-Karagwe-Ankalan褶皱带是非洲中部东部的主要地质特征之一。它可能是最著名的重要锡和钽-钽矿化的所在地，与后构造花岗岩，伟晶岩和脉有关1，2。在该带的Kibaran部分，用铷-锶方法对来自四个花岗岩基（Bia Mountains、Kibara Mountains、Bukena-Manono和姆万扎）的构造变形花岗岩、非变形花岗岩、伟晶岩和脉岩进行了年代学研究。
THE Kibaran–Burundi–Karagwe-Ankolean fold belt is one of the major geological features of eastern central Africa. It is perhaps best known as the seat of important tin and niobium-tantalum mineralizations, occurring in association with post-tectonic granites, pegmatites and veins1,2. In the Kibaran portion of the belt, geochrono-logical studies have been carried out by the rubidium-strontium method on tectonically deformed granites, on non-deformed granites, and on pegmatites and veins, from four granitic batholiths: Bia Mountains, Kibara Mountains, Bukena-Manono and Mwanza.
