Abstract: The main tectonic evolution time of the Bangweulu Block since the Pan African tectonic activities was studied in this paper according to the zircon fission track method. The Kasama—Nondo is located at mid-eastern Bangweulu Block of northeastern Zambia. Bangweulu Block which is mainly composed of basement and sedimentary rocks was comprehensively affected by northeastern Paleoproterozoic Ubendian Belt, southeastern Mesoproterozoic Irumide Belt, southwestern Pan-African Lufulian Belt and northwestern Mesoproterozoic Kibaran Belt. In order to study the geological characteristics and tectonic activities in Kasama—Nondo, some fresh rock samples from Mbala Formation of Mporokoso Group and lower Kasama Formation of Kasama Group were took and the 4 detrital zircon fission track ages are between (482±42) Ma and (351±32) Ma. The ages might be divided into two groups, i.e. 488-441 Ma and 375-293 Ma, which respectively correspond to the main periods of the Ordovician and Carboniferous. Compared with the ages from Lufulian Belt, Zambezi Belt, Damara Belt and Malawi Lake area and so on, the tectonic activities of Ordovician and Carboniferous in mid-southern Africa involve wide area and the tectonic activities of Bangweulu Block may pave the way for the later disintegration of Gondwana Block. Few data on Bangweulu Block are available and the results can provide important information for the future work in the Kasama—Nondo.
