The Bunu area in Southwestern Nigeria lies within the Basement Complex that forms part of the Pan-African platform of the crystalline rocks. The complex lies within the vast Trans-Saharan Pan African mobile of Neoproterozoic. The belt is characterized by voluminous post-collision granitoid plutons that are well exposed around the study area.

Africa - Geology, Plate Tectonics, History: The African continent essentially consists of five ancient Precambrian cratons—Kaapvaal, Zimbabwe, Tanzania, Congo, and West African—that were formed between about 3.6 and 2 billion years ago and that basically have been tectonically stable since that time; those cratons are bounded by …

As discovered by the radio-isotopic dating, the time span for the development of the Kushaka greenschist belt is between Kibaran and Pan-African orogeny episodes [1, 3, 4, 7, 8].Likewise, the age of the syn-to-late-tectonic granite rocks in the greenschist belt matches well with the Pan-African orogeny events (600 ± 150 Ma) [1, 7, 8].The granite …
