The southern East African Orogen is a collisional belt where the identification of major suture zones has proved elusive. In this study, we apply U-Pb isotopic techniques to date detrital zircons from a key part of the East African Orogen, analyse their possible source region and discuss how this information can help in unravelling the orogen.U-Pb sensitive high-mass resolution ion microprobe (SHRIMP)...
The island of Madagascar straddles the poorly understood eastern margin of the East African Orogen, which is characterised by a high-grade gneissic basement that was structurally and thermally reworked during the Neoproterozoic collision of the Dharwar craton of India with the Congo/Tanzania/Bangweulu craton of Africa. An east-west traverse across the eastern margin of the Antananarivo block of central...
