Weis, D., Liégeois, J. P., & Black, R. (1987). Tadhak alkaline ring-complex (Mali): existence of UPb isochrons and “Dupal” signature 270 Ma ago. Earth and planetary science letters, 82(3-4), 316-322. doi.org/10.1016/0012-821X(87)90205-6
Köppen climate type:
The northern part of the complex, which is 15 km from east to west, is obscured by Quaternary sediments. An outer incomplete ring and the arcuate disposition of some rock units are indicative of a ring complex. The intrusion is emplaced in 2000 Ma Eburnean gneisses and granites.
